Hi MT-LB
Can you take another picture of the manufacturer's mark so that it is in focus?
Thanks

I think it's "BBH" for: Benjamin Berkeley Hotchkiss

The shell is for calibre 37x208, see here: https://www.bocn.co.uk/threads/french-37mm-mle-1929.107992/.

I think it was made for export? According to https://quarryhs.co.uk/ammunition-data-table/ it was a anti-aircraft gun.

The shell is hollow and the base is screwed in. Notice the two key-holes.
