I looked at a canoe a few months ago that from all but one factor looks like an Old Town OTCA or Yankee. Serial number is 18290-16. The confounding factor is that it has the typical heart-shaped crowned short decks of a BN Morris. The stems are not splayed and look like typical OT stems. The canoe was extensively repaired years ago and the repairer has passed away, so is unavailable to ask if the decks are original. Is this a serial number consistent with Old Town? Did Old Town ever finish off canoes for Old Town (or vice versa)? Sorry, no photos are available.
