I have located a 1938 or 1939 vintage Mauser MM410b about an hour south of me. It has been slightly "bubbified", but appears to be matching numbers based on photos I have seen. It is not in the original stock, the current owner has misplaced the mag, and the bolt handle has been modified for scope clearance by either cutting / rewelding or heating / bending. I can live with the wrong stock for a while - it superficially resembles the original. Anyway, does anyone have an idea on cost to restore the bolt and/or who can do the work properly? Thanks.
