Hi Jim,
Could you indicate the year your gun was made or serial number such as # 754xx ???
1. The Rifle N proof mark is that of the subcontracting firm, SIG Neuhausen.
2. The various Letter/Circle stampings are of various Swiss parts inspectors...which could be either federal inspectors or civilian contractor inspectors.
3. The CN+ stamping denotes some use of an alloy in the part.
4. I do not know what the "S&Co" stamping is...sorry.
