This is an exceptionally interesting mid 19th century Pennsylvania over and under percussion combination gun utilizing a swivel, or turnover, breech system that allows a single lock to fire either of two very different barrels. One barrel is approximately \u003cstrong\u003e.34 caliber\u003c\/strong\u003e with eight groove rifling, while the second is an approximately \u003cstrong\u003e21 bore smoothbore\u003c\/strong\u003e barrel intended for shot.

Under federal law, it may generally be owned within the United States without a special license or permit and does not require transfer through a Federal Firearms Licensee. However, state and local laws may vary. This firearm is sold solely as a historical collector’s item and has not been test fired or inspected for firing safety by a professional gunsmith. Any mechanical or bore observations provided below describe only its present condition and should not be interpreted as confirmation that the firearm is safe to load or fire. The purchaser is solely responsible for complying with all applicable federal, state, and local laws.\u003c\/p\u003e\n\u003cp\u003eSwivel breech combination guns were a particularly ingenious solution to the needs of the 19th century hunter. Rather than carrying both a rifle and a smoothbore, the shooter could rotate the paired barrel assembly and bring either barrel into alignment with the single percussion lock. This allowed the same arm to fire a rifled projectile for larger game or a shot charge for birds and small game.\u003c\/p\u003e\n\u003cp\u003eAmerican swivel breech arms were built in a wide variety of configurations, including rifle over rifle and rifle over smoothbore combinations. Surviving Pennsylvania examples demonstrate that this unusual action type was well established among American sporting gunmakers during the percussion era.\u003c\/p\u003e\n\u003cp\u003eThis example measures approximately:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e48\" overall\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e32\" double barrel assembly\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe rifled barrel measures approximately \u003cstrong\u003e.34 caliber\u003c\/strong\u003e and retains \u003cstrong\u003eeight groove rifling\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe second barrel is smoothbore and measures approximately \u003cstrong\u003e21 bore\u003c\/strong\u003e, giving the owner a genuinely useful combination of rifle and fowling gun in a single arm.\u003c\/p\u003e\n\u003cp\u003eThe barrel assembly is retained in its selected firing position by a trigger style locking catch beneath the barrels. Releasing the catch allows the complete over and under barrel group to rotate so that the desired chamber and percussion bolster can be brought into alignment with the lock.\u003c\/p\u003e\n\u003cp\u003eThe upper surface of the rifled barrel is marked:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eS ✳ C ✳ DANNER ✳ PA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe rifle came to us attributed to \u003cstrong\u003eSilas C. Danner of Carlisle, Pennsylvania\u003c\/strong\u003e. We have not located sufficiently reliable documentation confirming that identification, so we preserve the barrel marking exactly as found and describe the gun as attributed to S.C. Danner rather than assigning the maker's full identity as established fact.\u003c\/p\u003e\n\u003cp\u003eBoth barrels are additionally marked at the breech:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eWORLY\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is an especially interesting marking. Pennsylvania gunmaking references record members of the Worly or Worley gunmaking tradition, including makers associated specifically with over and under barrels for percussion rifles. The exact individual responsible for these barrels has not been established from the marking alone, but the name provides another potentially important avenue for research into the gun's Pennsylvania manufacture.\u003c\/p\u003e\n\u003cp\u003eThe side lock is marked:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eJOSEPH\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eGOLCHER\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe lock plate is particularly attractive, with decorative engraving that includes a small hunting scene depicting a hound beneath a game bird in flight.\u003c\/p\u003e\n\u003cp\u003eGolcher marked locks are widely encountered as commercial trade locks on American percussion rifles. Members of the Golcher family were active in both the British and American gun trades, and surviving Pennsylvania sporting rifles frequently carry Golcher locks even when the complete firearm was built by another gunsmith. For that reason, the \u003cstrong\u003eJOSEPH GOLCHER\u003c\/strong\u003e marking identifies the lock maker or supplier rather than the maker of the complete combination gun.\u003c\/p\u003e\n\u003cp\u003eThe gun is fitted with a substantial American black walnut butt stock rather than a full fore stock. This exposed barrel arrangement is commonly encountered on swivel breech rifles because the complete barrel assembly must rotate freely. The stock incorporates a carved cheekpiece on the left side. A small white metal escutcheon is inset into the cheekpiece, with another small white metal escutcheon positioned on the back of the wrist.\u003c\/p\u003e\n\u003cp\u003eThe brass butt plate is deeply hooked in the target and sporting rifle tradition, helping secure the butt against the shoulder during deliberate offhand shooting. The right side of the butt stock carries an oval brass patchbox. Its hinged lid remains functional and opens correctly. The remaining furniture is primarily brass alloy. The trigger guard has the familiar pistol grip style rear extension seen on many Pennsylvania percussion sporting rifles and is relatively restrained in decoration while still being well made.\u003c\/p\u003e\n\u003cp\u003eBrass ramrod pipes are mounted along both sides of the barrel group. Interestingly, one set is noticeably larger than the other, consistent with the very different bore diameters of the two barrels. The rods presently installed appear to be later display replacements rather than original working ramrods.\u003c\/p\u003e\n\u003cp\u003eThe gun is equipped with a functioning \u003cstrong\u003eset trigger\u003c\/strong\u003e. The rear trigger must first be pressed until it engages, after which pressure on the front trigger releases the lock. On this example, the lock will not release unless the rear trigger is first set. The lock does retain a half cock position, but if the set trigger is engaged while the hammer is at half cock, pulling the front trigger can cause the lock to release. The trigger therefore should not be set until the hammer is at full cock. \u003cstrong\u003eThis is an important mechanical condition issue and is disclosed exactly as observed.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth barrels have percussion bolsters with cleanout screws. The screws are presently frozen, and their slots show deformation from previous attempts at removal. The percussion nipples appear to be comparatively recent replacements and show substantially less corrosion than the surrounding bolster and barrel surfaces.\u003c\/p\u003e\n\u003cp\u003eThe rifled barrel is fitted with a simple fixed rear sight and a brass blade front sight mounted in dovetails. There is also a threaded aperture in the barrel tang and another sight dovetail farther forward on the barrel. These may have accommodated an additional target or peep sight arrangement at some point, although the original configuration cannot presently be established.\u003c\/p\u003e\n\u003cp\u003eThe smoothbore barrel carries only a front sight, appropriate to its intended use with shot.\u003c\/p\u003e\n\u003cp\u003eThe .34 caliber rifled bore is in \u003cstrong\u003every good condition\u003c\/strong\u003e. The eight groove rifling remains clearly defined and the interior is partly bright. There is light wear to the lands from use, together with several small areas of old powder fouling and oxidation.\u003c\/p\u003e\n\u003cp\u003eThe 21 bore smoothbore barrel is clear and shows light overall evidence of past fouling and oxidation.\u003c\/p\u003e\n\u003cp\u003eThe exterior metalwork has developed an attractive aged gray and brown patina. There is evidence of old oxidation that has been cleaned away, together with more noticeable corrosion around the percussion bolsters, but we do not see major destructive rust damage.\u003c\/p\u003e\n\u003cp\u003eThe American black walnut butt stock remains in very good condition and has developed a handsome red brown color with a pleasing waxed surface. It shows the expected light dents, scratches, and handling wear but no major structural damage or significant stock repairs were observed.\u003c\/p\u003e\n\u003cp\u003eWith its unusual rifle and smoothbore combination, rotating over and under barrel assembly, \u003cstrong\u003eS ✳ C ✳ DANNER ✳ PA\u003c\/strong\u003e marking, separate \u003cstrong\u003eWORLY\u003c\/strong\u003e barrel marks, engraved \u003cstrong\u003eJOSEPH GOLCHER\u003c\/strong\u003e trade lock, working set trigger, hooked butt plate, patchbox, and strong rifled bore, this is an exceptionally interesting example of inventive Pennsylvania sporting gunmaking.
