First, that is delicate rifle – it is darling. (It has the feel of a child's or woman's gun.)
I noticed several things about the rifle that I wanted to ask about.
The barrel looks to be wedged by the nose cap but pinned in the fore-stock. I don’t know if I have noticed anything like that before.
A brass screw to hold the lock on and a single one at that - brass is very soft, Seems odd to me.
The lock looks to be mounted VERY high on the barrel – pushing into the angled flat (it also looks to be very wallowed out too,) but, has anyone seen that before? It seems very out of proportion to the barrel size. (it does add to the thinness of the rifle though.)
But the BIG question I have: it looks like the wrist is checkered. I thought that was a late 20th century thing? Are there any other examples of that in the Federal or pre-Revolutionary period. (I am guessing, and the library didn’t say, or I missed it, that this is a very late flint period gun).
