Im going to look at a 1953 jp sauer and the owner doesn't seem to know much about the firearm. All he could tell me was that his father bought the gun in 1953 for $450.00 and that he acquired the gun in 1977. He said that the firearm was used very little and looks like new. The question I have is, does jp sauer have a quality or grade system? If they do could anyone fill me in.

thanks for any help.
