On Fourth Variation (1923 to 1929) Model 1914's were any internal, small parts, other than the sear, numbered with either full, last 3 digits or last 2 digits of the gun's serial number?
Also, did Mauser continue to fire blue the trigger, extractor, grip screws, safety lever and pushbutton and takedown rod (barrel pin) face?
Great thanks in advance for any replies.
