I got my first Ruger Standard Auto from an old trapper in Nevada in 1981. It was an early red eagle pistol, 4-digit serial number. I couldn't even begin to guess how many rounds had been fired through it before I got it, but it was the most inaccurate pistol I ever owned. I traded it straight across for a Ruger Mark II Government Target model in about 1988. The guy wanted it so bad he gave me a new in the box gun for that old piece. I thought I was the best barterer in the world (until I found out what the pistol was worth a few years later 
).
