In 1965 I was a married graduate student and my wife was still in college, so we obviously didn't have a lot of money. I managed to scrape up $85 to buy a used Colt SAA 2nd generation in .45 Colt, near mint condition. At that time these guns were still in production and had a list price of $125 brand new, so they were not collectors items.
In 1966, I read an article in a gun magazine about the S&W Model 39 and just had to have one. They were hard to find at the time, but I got one from a dealer in Connecticut who took my Colt in trade along with a Lyman 454190 mold and a set of dies. I own a lot of guns now, but that Colt is the only one I regret selling. I still own and shoot the Model 39, but I wish I hadn't read the article about it!
