Old Town serial number 135461 was a 16-foot CS HW model with open spruce gunwales, ash decks, and a keel. You're right, it was built in 1942 and shipped to Claremont, N.H. The original color was dark red.

This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. A description of the project to preserve these records is available at http://www.wcha.org/ot_records/ if you want more details. I hope that you and anyone else reading this will join or renew membership in the WCHA so that services like this can continue.
