1882 - 1886 pat. cannon shell


I would appreciate any information regarding the above old shell. It has a straight case. It looks like it has never been loaded.

It is 16 1/4 long, 3 1/2 od, 3 11/16 rim od, 11/32 rim thickness.




The opening of the above shell is slightly belled to accept a projectile.

There are no other markings on it.


The shape of the rim is odd.

I would speculate (with no evidence other than a gut feeling) that it may not be a normal artillery shell, but rather some sort of pyrotechnic device, or perhaps a line throwing related item.

Possibly not even a “cartridge” at all but some sort of element from a steam or hydraulic device.

Remember, my free advice comes with a full money back guarantee!


Greg did you try looking on the US Patent website?
