I have a 1413 Model 54 Super Match that I purchased new in 1977. In the mid-1980s I had the action threaded and a stainless barrel installed. The work was done by a gentleman with last name Foster and I recall he was in MN. But for the life of me I can't recall his first name. I am considering selling the rifle and would like to correctly give credit to the work. Any help in jogging my memory would be appreciated.
