This is an incredibly rare projectile and casing for the 3-Inch M1917 anti-aircraft gun, a very short-lived variant. It was only deployed in limited quantities on fixed mounts. It was soon supplemented by a newer mobile model, the 3-inch M1918 anti-aircraft gun. Very few were manufactured; as of April 1919, there were a total of 116. Its use was highly limited.

The projectile itself is stamped on the body:

A.G. 178-X
43060-3
(FLAMING BOMB) SWACO

The fuze, which is still in its original configuration with the separate parts moving in their own directions, is stamped RH 18 ANTI-AIRCRAFT LOT 2192 13, denoting that it is in particular made for use with the anti-aircraft gun. The projectile can still be removed from the casing for inspection of the interior. The bottom of the casing is stamped:

AMM. LOT. 52-19-E
3 IN. MARK I
GUN MOD. OF 1903-17
LOT-100-1 F.P.S.

When standing together, the round measures 39 ½” tall with a 4 ⅝” base diameter. 

An outstanding and rare round, ready for display.
