Just wondering if anyone can help, I have what I believe is a Harry Quinn frame in 531 tubing. See the photos below. The frame number is stamped 1 and can just be made out on one of the photos. Someone has picked the lugs out in white paint and not done the best job. I was going to get this restored and built up for my dad but I don't want to spend the money if it's not an original.
