I'm not sure the chainguard on the blue bike is original to the frame, but I could use it for another 20" frame that I know for sure it was used on. Would you be interested in selling or trading for that chainguard. I've been looking for that guard since I bought this bike frame off the Schwinn forum two years ago.
Also I would be interested in finding out what the serial number is on the rear dropout on the orange bike. It might be hard to read since the bike appears repainted. Paint might be too thick. I know that frame/chainguard was made by Huffy, but the serial number can sometimes tell you if it was made for Sears, Western Flyer, or just for Huffy.
