Thanks to all for your comments.
Griz, of all the pictures I have seen, the trigger guard has been of iron and screwed to the surface of the stock. I have on had the opprotunity to examine one original Trade Gun.
The original I looked at had a wopping 52" barrel. The barrel was swamped, looked to be about 24 gauge. The trigger guard was very typical of the Northwest gun, althought very thin. The serpent side plate was not inleted. Pictures of some side plates have clearly been inletted.
He is a picture of the left side of my gun.
I inletted my side plate about 1/16th of an inch.
Doc, I screwed by butt plate. After doing so I regretted it. I cant claim to be much of a blade smith when I have a garage full of forges and anvils. It would have been nice to say that I forged my nails for the job. I have been giving thought to contacting TVM, ordering a new butt plate and nailing the butt plate onto the stock.
I left the sight off until I go to my property in SE CO. After I get some idea of how it will shoot the sight will be silver soldered in place.
Your interest and comments are very appreciated, thank you.
