Rear Frame Well. The machining marks are unique to Krieghoff manufacturing. Some will try to draw similarities between ERFURT and SIMSON given the theory of the â??same toolingâ? and milling machinery - but in fact, Krieghoff used their own pattern, on their own â??newly designedâ? machinery. The HK process gave faster production, better Q&A with a superior finish then either ERFURT or SIMSON (credit to H. Krieghoff who engineered the design change). Therefore, the HK process is readily able to be identified:
Front Frame Well. Again, the machining marks are unique to Krieghoff:
Witness Marks This 1938 HK - sn: 9938 has no witness marks, but 2 are noted as having witness marks.
Frame Internals The
hold open, properly proofed. Another area where I disagree with Mr. Gibson. This part is not serialized â?? and frequently, found NOT be serialized in this serial range:
Sear Bar. This sear bar is NOT numbered, simply proofed correctly. Given the other tell-tales of this 1938 - this is correct, although counter to Mr. Gibson's theory on sear bar numbering.
Toggle, Train, and Top End Condition of the chamber top, breech block and middle toggle link. Note the distinctive HK polishing methods.
