John sent in this nicely outfitted Sears Free Spirit FS10. He is looking for some information on the manufacture date of this little beauty. John, I’m not sure this is an ’89 as you speculate. I would think it is older than that. If the seat is original, you might check the underside for a date-of-manufacture stamp. I have found manufacture dates on a few of my OTS seats, which would at least be a rough estimate for the rest of the bike. If anyone else has any advise or experience deciphering the serial numbers on Free Spirits, please leave a comment.
I’m hoping someone can tell me when this bike was manufactured. This Free Spirit FS10 was in a thrift shop and looked as if it had been used very little and stored out of the weather and direct sunlight. I have been all through it and except for a noisy freewheel it now runs well. The numbers on the bottom bracket are 489-471370 and 4C11C721. I suspect the “Cs” may be poorly stamped zeros. My guess would be a manufacture date of 4/1989. It has a Falcon RD and the alloy brake calipers are Polygon. The only other alloy items are the shift and brake levers. The frame is lugged with gold pinstripes outlining the lugs and matching the gold Free Spirit and and FS10 labels.
