What do you Collect?

What's the diameter of the shell base in millimeters?? Because its almost has wide as the projectile itself (just a bit wider), it should give a good indication of the size of the cannon.



For the U.S at least, I think the largest one piece round was a 5 inch naval gun (slightly larger than a 120 mm cannon). The 155 mm cannon and 8 inch howitzer had separate projectiles and powder charges. Big naval cannons as well, although I don't know about heavy cruiser naval cannons (8 inches).

The base of the shell is 63mm. It has 18 on it so I am thinking 1918, but I do not know.

It should have the size of the gun if its american. Does it have any other writting on it? how tall is it?? I have a 40mm navy deck gun round (minus projectile) that looks like that. Its about 14 in tall and close to 2 in wide. ( don't have a tape measure with me). 18 would normally mean 1918. But if its foreign, I'm not sure.
