is this a RAMROD

[fernando]

No Richmond, this ougth to be something but not a cannon ramrod.
That thick part would have to be the front, whereas it has all ingredients to be in the back, namely a grip. You don't have a rammer with a rounded head and even with that little portrusion, all so much in the shape of a handle.
Also the brass connection is not adequate for a cannon rammer, unless you were talking about some contemporaneous miniature/replica.
