Unidentified Brass Plug

Thanks for the idea - I don't think that we had any Naval cases with that size of hole. Depotman
Excellent! Thank-you very much for your 'lateral thinking'! It is exactly the same thread as the 'standard' primer for the 13-pr, 18-pr, 25-pr, 3.7 -inch AA shell cases; and many Naval shell cases as well.
The next question is what was it used for? My guess is to hold the 'used' shell cases as they went through their refurbishment processes including cleaning and perhaps some of the heat treatments.
If anyone has any detail descriptions of the processes, including photos, they may finally solve the query. Depotman
Nice to hear 
. We had similar plugs but made from Zinc for naval cases (may be others too). These were used in the ammunition arsenals (where the cases were filled with powder) to keep the primer hole clean and probably also to keep moisture away and for safety reasons. When the cartridges were made ready for delivery those plugs were replaced with real primers.
