This is a good original Vietnam War era U.S. Navy \u003cb\u003eMk 76 Mod 0 25-pound practice bomb\u003c\/b\u003e, now completely inert for display. The exterior has been entirely repainted black at some point, obscuring the original arsenal markings and preventing a more precise manufacture date from being established.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUnloaded or dummy grenades, artillery shell casings, and similar devices, which are cut or drilled in an BATF-approved manner so that they cannot be used as ammunition components for destructive devices, are not considered NFA weapons. This example is in total compliance and is NOT AVAILABLE FOR EXPORT.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe 25-lb PB Mk 76 Mod 0, now obsolete, has a tear-drop shaped, cast-metal body which is centrally bored. The tail-tube assembly fits into the end of the bore. The conical afterbody covers the tail-tube assembly and is threaded to the body. The two sections are staked together to prevent unscrewing. The fin assembly is welded to the tail tube. Firing Pin Assembly Mk 1 Mod 0 and the signal are assembled into the bore of the body and secured in place by a safety cotter pin (not present on this example).\u003c\/p\u003e\n\u003cp\u003eIn the Mod 0 a single lug is positioned just forward of the center of gravity of the bomb. Some bombs of early manufacture have a suspension lug with a small opening which precludes use of the bomb on Shackle Mk 8 All Mods or Aero 14 and 15 series racks. Later manufacture provided lugs with a larger opening that permits use on this type shackle or rack. Activities may replace the older type lugs with lugs having the larger opening. The threads in the bomb body should be cleaned after the smaller lug is removed. Glycerine litharge cement should be applied to the threads to hold the newer type lug in position.\u003c\/p\u003e\n\u003cp\u003eThe Mod 1 is designed for air-burst firing only. The Time Fuze AN-M146E3 (not present) is used to fire the Signal Mk 4 Mod 3 which is seated in the bore of the body section. A setscrew is threaded into the nose of the bomb to retain the fuze and signal. Smoke produced from the detonated signal is discharged rearward through the tube of the fin assembly.\u003c\/p\u003e\n\u003cp\u003eIn the Mod 1 a single suspension lug is threaded into the bomb body just forward of the center of gravity and cemented in place. Two 3\/8 inch indexing holes are drilled into the body to assist in the proper positioning of the bomb in the Aero 8A Practice Bomb Container.\u003c\/p\u003e\n\u003cp\u003eThe Mod 2 is similar in appearance and functioning to the Mod 0 except that two 3\/8 inch indexing holes are drilled into the body at the center of gravity to assist in the proper positioning of the bomb in the Aero 8A Practice Bomb Container.\u003c\/p\u003e\n\u003cp\u003eThis lovely Mod 0 has been entirely repainted black and no longer has any of the white arsenal stampings present. Unfortunately the suspension lug is missing, but there is a pin attached at the tip, and it sits well on this end for display. One of the four fins has some denting, but otherwise the shape is well-retained.\u003c\/p\u003e\n\u003cp\u003eThe combination of the \u003cb\u003eheavy cast-metal Mk 76 Mod 0 body, central signal bore, welded four-fin tail assembly, surviving early configuration, and fully inert condition\u003c\/b\u003e makes this a good representative example of U.S. Navy Cold War aerial bombing-training equipment. The missing suspension lug, damaged fin, and modern repaint are important condition points, while the underlying structure remains characteristic of the original Mk 76 Mod 0 practice bomb.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":45751854858309,"sku":"ONAC26B015","price":295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONAC26B015__01.jpg?v=1789403071","url":"https:\/\/www.ima-usa.com\/products\/original-vietnam-war-era-u-s-navy-mk76-inert-25lb-practice-bomb-repainted-black","provider":"International Military Antiques","version":"1.0","type":"link"}
