Hi Mike,
I disagree. Why do you think it is English?

Because it isn't anything else!
Everything about it is english The engraving on the mainspring, the hidden sear spring screw, the shape of the plate, cock, pan, etc. The date of it could be dicey, I would assume pre 1770's untill you consider the wheel on the frizzen spring. of course it wasn't unusual to have things like that added later.
I believe the engraving was done outside of London proper. The style and execution is a little hinckey and probably done in one of the more provincial towns.
What I want to know is what it was off of. I'm thinking possible and over/under pistol......
I'll trundle through the snow later and look at some of my English gun books, they are all out in the shop.
