You may want to review the information at http://forums.wcha.org/showthread.php?791 to see if you can clarify these numbers. Wooden canoe serial numbers are usually the same in each end and don't typically have embedded letters (with some exceptions). The most common format is a series of digits which are the sequential serial number followed by a space then two digits which are the length of the canoe in feet. Canoes built after 1972 will have a hull identification number on the starboard stern that starts with three letters and ends with an encoded date as described at http://www.boatsafe.com/nauticalknowhow/hin.html in more detail. Can you attach a picture of your serial numbers and confirm if they are both from the same canoe? Thanks,
