Just received a WWI Russian 3 inch (76.2mm) HE with a 3GT PD Fuse made by Bethlehem Steel Company. I was wondering what the correct color for the round should be and what markings, if any, should be on it. Doubtless, if you saw the round on GB (76.2 USSR AA), you can tell that the casing is, as stated, an M1931/38 AA casing. Luckily the round was not the US 75mm as described, but the Russian M1916 round and I'd like to return it to it's correct color scheme. Also, How hard is it to find a correct casing for this shell? Cheers, Bruce.
