There is no rust on the firearm from what I can tell - but it does appear some of the lubricant used in the past has gel'd and needs to be thoroughly cleaned. It's been parked in a safe for at least 10 years. I remember shooting it once when I was a kid - probably 20 years ago.
From what I've read, it was made by J.P. Sauer and Son and imported from Germany before they merged with Sig.
