Hi Folks, Got this bike yesterday from a bike co-op that gives bikes to the homeless and those in need. I traded them six bikes that were more modern. The bikes I traded them were freebies, so other than my time I got this "Colson" for nothing. The lady I spoke with called it a Colson, but I have my doubts. No headbadge of course. All the research I've done so far have not found any matches or similarities to this serial number: K205731 Can you guys help me? I'm new to the old-bike game.
