I just purchased a 13.5 foot Peterborough Canoe that the owner thinks is from 1952. I found the serial number on the stem located at the stern and it looks like 2078 (see attached image) although the 8 also looks like a backwards three and the 2 looks like a different stamp than the other numbers. This serial number was not listed on the Wooden Canoe Museum website. Any help that could be provided would be most appreciated.
