Can you post pictures of the serial numbers from each end? The tips at
http://forums.wcha.org/showthread.php?791 may help if you are having trouble reading any of the digits. The build record below for serial number 132030 shows a 17 foot long canoe. I also checked 132080, 182030, and 182080 but didn't find any 20 foot long canoes. Which digit is the least clear? Thanks,
Benson
