you have a commercial FN series 200 action with a replacement trigger. The trigger is from a reputable company. The same action was used to build J.C. Higgins sporters during the fifities and early sixties. It is an excellent action.
The rifles were sold at Sears Roebucks and other department stores. they were sold as FN commercial rifles as well.
The scope mounts and scope should be offered on an auction site. The mounts may be worth more than the scope. If you are ditching the stock, why not sell it to me?
