I was cleaning my house and found two scopes I didn't even know I had. I don't remember buying them. One is an old Weaver K6 it is a steel tube 6X40mm not the new 6X38mm. The other one is a Tasco #615W 1.75-5X40mm. Does anyone know where I can send the Weaver to have it cleaned and worked on. I want to restore it and the "new" Weaver doesn't work on the old US scopes.
