I was thinking about restoring an old bike I bought years ago, but I don't know what kind it is, to the best I could see, here are the numbers that was on the bottom: MOTSX (the 0 is a maybe) then 45 402 these were slanted beside the MOSTX, then these below were under them. Mod 702 (almost sure it was a 7) then the numbers under Mod 12 12 86 (and spaced like that). I know it's a 26" boys, but I have never seem 2 small bars for top on a boys bike, plus they are not welded on frame under seat, but sit in special cups like a U that are welded on. I just wanted to make sure it was worth restoring. It looks to me like it's from the 50s or 60s. It has Schwinn on hand grips, but anyone could have switched those. Its in great shape, and won't take a lot to fix. Here a picture Thanks Tom Barnes
I was searching for bikes and I found one identical to this one: it was a VINTAGE 1959 MURRAY SEARS FLIGHTLINER, all it was missing is the little silver bar that goes above the front fender that clips into that little silver clip on the bottom of the headtube. Some may have had headlight tanks, the one I found didn't. So it could be a 59-60?
