Our serial number scans only go through 210999, which shipped in the mid-1970s. You can send $3 to Old Town for part number 01.1332.0100 as shown at http://oldtown.wcha.org/parts.html to get a copy of the build record. The more recent records don't contain nearly as much information as the old ones, and Old Town discontinued record keeping altogether in the '90s. Please reply here if they are not able to satisfy your request.
If you are unsure whether your canoe is an Old Town, please post pictures and maybe someone can identify it.
