Here is a brass shipping cap that is missing the sealing strip that holds it to the round, but still has the solder. The bump on the side is similar to the ones I've seen on the M1907M (both 75mm 21 second and 6" 31 second), M1914-1915 for the 155mm and the 3" AA "S" Fuze (thanks Brian Keith and Shelldude for reminding me of that one), and the profile is most similar to the "S" Fuze, but not quite there. Does anyone have a positive ID on it? Any help would be appreciated. Cheers, Y'all, Bruce.
