I've reached out to many sources and asked opinions of many "experts" regarding an inherited k98. The responses have been drastically different leading me to believe many in the market are unscrupulous...but on the positive side, I'm learning a lot as I go along. On my 1939 Steyr (code 660) the serial numbers on the barrel, receiver, bolt handle, firing pin, butt plate and stock are all matching. The last two digits of the serial number are stamped on the safety, cocking piece and bolt sleeve. My rifle was purchased from an army surplus store in the late 1950's and remained in the family safe for over 60 years so no one has messed with it. Was the K98 market in the 50's such that someone would have gone through the trouble to acquire unmarked parts and stamped them to match? (I doubt this scenario as my father bought the rifle for less than $50 at the time) If it is a post war refurb as speculated by some, would whomever have stamped numbers onto all the parts or have just refinished the rifle? Is it normal for a rifle of this period to just have the last two numbers of the serial stamped onto the smaller pieces or is that a post war practice? Another puzzling feature is the trigger guard does not have the capture screw cut out yet it is clearly stamped with the correct serial number? Wouldn't a rifle of this vintage been originally equipped with the capture screw trigger guard/housing?
