Looks like a cup, found it on a beach in the UK. Solid iron and very heavy, signs of what looks like where a handle used to be, if it is a cup would like more info. Thanks!
""Breech-loading swivel guns were developed surprisingly early, and were used from 1370 onward.[SUP][8][/SUP] The guns were loaded with mug-shaped chambers, in which gunpowder and projectile had been filled in advance. The chamber was then put in place, blocked with a wedge, and then fired.""
many of them did have a handle that facilitated the loading of the chamber into the breech of the gun and you describe it looking like it once had a handle.
Hi, The museum is quiet bad, and have failed to identify it. I forgot to say, it has a solid flat bottom with no hole in it. Its very heavy solid iron and is about 25 cm tall and 15cm wide.
Since you don't seem to be getting anywhere with the present picture, might I suggest removing the oxidation through electrolysis or some other method?
Might bring out some details that are not currently visible.
