I buzzed into a flea market today and found a stack of Frigidaire Tech Manuals in a box and bought them from the guy. They start in 1959 for the 60 models and go up to 1967. If anyone needs any tech info from these years, let me know and I'll take pictures of the pages you need or xerox them and send them off to you or whatever you need.
I'm sure I didn't get all the tech manual for the whole span of time, but there are various manuals for various appliances. Some are for fridges, some are for washers, some are for ranges, etc.
