Adam:
Per your request, attached is the build record for 121819 which was sent as a replacement when the canoe you now have was first returned, damaged, by the original purchaser. The canoe seems to have been damaged in transit to its original destination. From what I have seen of OT build records, OT was very good at making quick replacements to satisfy their customers, then working out a damage claim with the railroad carrier. Your canoe was then repaired and re-sold to another customer, likely at a discount. It was subsequently returned a second time for further repairs at the OT factory. That was probably from 'wear and tear' during use.
