I marvel at the ease and skill of those members that respond to the requests for serial number searches. Has anyone figured out how to search backward with details of the canoe's history to find a serial number? I bought a canoe 30 years ago and got the build record from Old Town. I then sold the canoe and lost the printed record. A few years ago I bought the canoe back and in the meantime the serial numbers have turned into a bunch of scratches. I have tried smoking, rubbing, wetting and lighting but no luck. I do remember that the canoe is a 17' HW sold originally at Staff Jennings boats in Portland, Oregon. Digging through many layers of paint the first coat on the present canvas was blue. Staff Jennings still operates in Portland and they established the business in 1929. I have tried searching through the build records one by one, looking for a 17' HW sold by Staff Jennings in Portland. No luck. I think I have established that Staff Jennings did not start selling Old Town canoes immediately. I may have over- looked the right build record or perhaps I have not gone far enough forward from 1929. I may be wrong but there appears to be five digits to the serial number. Any suggestions for improving my search methods before I go blind would be very much appreciated. Thanks to the experts. R.C.
