I came across this thread in searching for some information about Leonard bikes. From what I can gather he had some lower end bikes he sold out of a shop on St. Michel in Montreal, but he also made some custom bike. You can see some of the lower end ones for sale on Marketplace and Kijiji in Montreal from time-to-time. I picked up what the seller claimed to be a Leonard at the end of last summer from a guy who was desperate to sell his bike. It was a bit weird, but in the end the frame looked nice and the components were nice for the price he wanted. The bike was originally built for the guys father. They had it repainted for the son, but it is clear they did not have the original decals (I will attach pictures at the end). I have no idea when the repaint was done, but it sounded like it was more recent than 2007. So, I think Mr. Cheico had already passed away (I really enjoyed reading the comment from Domenico Cheico's about his father). It fit with what the guy who sold me the bike said. Anyway, I think my frame is from a more recent date than the one in the photo you guys attached. It has eyelits for the brake cable and braze on for the shifters. I put it in the early 1980s as it had a pat.81 rear derailleur. I was curious to see if you had a serial number. Mine has one etched by hand and it appears to be 1547, but it is hard to read. As for the tubing on the frame, I cannot tell, but the fork is tagged Columbus. Anyway, I enjoyed reading your thread and was wondering if anybody had any additional information. Here are some photos:
