I saw this listed on FB Marketplace in Montreal about 9 hours after the original posting. Seller had no idea what he had and it was just listed as a vintage bike for 500$ Canadian with a less than informative set of pictures and information. Nothing about the parts or frame size. By day 2 or so, the price was up to 1500$ or best offer and it was listed as a Cinelli, but with the same pictures and same information. Shortly afterwards, it was listed as sold. As the original OP stated, local collector figured it out and probably made a nice offer to the guy.
