whats up, i got this bike yesterday for 70 bucks serial number its almost gone can you tell the year just by the color? or perhaps chainguard n sprocket? please help and thanks in advance
I too recently picked up a Vintage Columbia Tandem. I put the year as early 70's or older based on condition and the fact it is a steel frame weighing, A LOT. I've been looking for a serial number and so far found this stamped on the bottom of the rear peddle bracket. Any input on age or other locations to location for a serial number is appreciated.
