If I am not mistaken it's a USN interwar practice bomb. I'll check later in my files.

This is a USA 3lb Mk23 Mod1 Practice Bomb , cast iron and used a 10ga Mk4 spotting cartridge paper or aluminium in the nose to make an impact signal.

One more request, anyone with a photo of the 10g MK4 spotting cartridge
Thanks

The 10ga NUBLACK is 6" long. Makes a flash and smoke to indicate where the bomb hits. Aluninium case is a later one.
