Welcome!
Pictures are needed-- a shot of the deck, a look at the profile of bow or stern-- a shot of the seat and thwart-style. It's also helpful to know where the serial number was located-- on only one or both stems, on a rib...? and is it impressed into the wood or is it on a metal plate?
Records that would connect the serial number to an original build record--- and thus provide an exact shipping date--- exist for only a handful of canoes. But serial number styles can help define what you have, and some companies coded information into their serial numbers. Hopefully, the many minds that inhabit these Forums can figure out what you have!
