Nope- There is another one here.
The very first rifle I ever built was a 50 caliber Sharon Trade rifle, it was a high school shop project when I was a Freshman in HS. It was stolen by a room mate a few years later.
I was absolutely elated when I found the complete unbuilt Trade rifle kit a couple years ago.
My 2 fullstocks are a matched pair, one is a flint and the other is a percussion. I have to wonder if they were possibly a father/son project- the rock lock shows fine craftsmanship and a nice eye for proportions whereas the percussion is of more bulky proportions.
In its day Hal Sharons barrels were arguably the best out there and the kits were of outstanding quality with L&R locks.
This is the pair of fullstocks
