That was the base I ordered through Fox Ridge Outfitters for that rifle. It is made for the T/C Hawkins and is off set so the hammer does not come near the scope. If you get one, be sure to put QD rings on the thing. After shooting I have to take Q tips and scrub all the little parts of everything to make sure it is clean. If I could pull the scope, I'd give it a water bath. Actually as soon as I get up to see my gunsmith friend I will have QD rings, although he likes Leupold. He said he'd make me a good deal on them if I got the scope as well. So I might throw a Leupold 2-7x33mm on it as well as the one power.

OK thanks I did not know they were weaver bases thought thompson had their own.
