My guess is that you have a Penn Yan hunter model as described at http://www.wcha.org/content/penn-yan-boat-company and elsewhere. There are no known detailed serial number records for Penn Yan, unfortunately.
Great, thanks for the information. Somebody had already started a restoration on this one and gave up on it. They were doing a great job too. I guess I'll be able to pick up where they left off and have an awesome canoe.
