57mm Nordenfelt

I have a case described as a 57mm Nordenfelt. Don’t know much about it. Case is 9 inches long. Below is a pic of the h/s.


I believe “EP” is “Ecole Pyrotechnique, Antwerp, Belgium”, although I haven’t seen written proof of that. “97” is the date (1897).

Thanks Falcon!

Anybody got a spare projectile for trade /sale ? Or even a pic of one?
