Hi Stuart..!

Ahhh - OK, thanks for the clarification.. I'm not aware of any Simson parts used in either Military production or during the "Commercial" era from HK. Post war - yes, on GI assembled HK parts guns - there have been quite a few Simson, Mauser, DWM, etc. parts that were used in their assembly.

Some time ago - there were some discussions regarding whether HK used parts from Simson when they acquired the tooling from that company. Given the visible differences between machining techniques between Simson and HK (frame, cannon, etc.), and supported by the fact that HK machining was fairly consistent throughout their dates of manufacture - point to virtually all the HK production was from their own parts, rather then parts acquired from Simson.

There was also some speculation as to whether Mauser or another supplier sent HK frame forgings for use in their production. However, since HKs are found in alloy metals, it would also lead to believe that HK produced their own frame forgings rather then receive them from another supplier.

Anyway - all of these theories are presented in Gibson's book and more info has been presented throughout the years in the NAPCA newsletter. BOTH (a NAPCA membership and Mr. Gibson's book!) are terrific investments - and will keep your mind spinning with what they contain/offer..!

Best to you!!!
