I have a canoe with a 4 digit serial identifier on it. It is approximately 17ft long, made of fiberglass, and has a metal stripped keel. It was originally red. I have no idea who the manufacturer was and would be interested in finding out. So would anyone know which manufacturer would only have a 4 digit serial number? Or simple way of finding out? I purchased it around 2004, however it was most likely 3rd or 4th hand and may have changed owners even more times than that.
