In my neck of the woods, this rifle would easily bring $1K+.... Don't underestimate Karl Kenyon's work. Especially if he barreled this rifle. His triggers are not that uncommon, and are very highly reguarded. Winchester even offered them as an option on some model 52 target rifles. Usually a modified rifle is not worth what an original is, but in this case I don't think so. Karl's work is that good. Get some Eley Tennex and post up some groups to show us, I'll bet we'd be impressed. All you need now is a 20X Unertl Programmer 200 scope and you would be all set!
Best regards, Kirk
