The Old Town with serial number 191605 is an 15 foot long square end model with a canvas covering, a keel, half ribs, and outside stems. It was built between October and November, 1972. The original exterior paint color was dark green. It shipped on December, 14th, 1972 to Acton, Mass. It may have moved to Milton, Mass. by April, 1975 when there was a previous request for a copy of this build record. Scans showing both sides of this build record can be found in the links at the thumbnail images below.
These scans and several hundred thousand more 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 will join or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have another number or manufacturer if this description doesn't match your boat. This model was not listed in the 1972 catalog but the 1971 catalog description of this model says "it has half ribs, oarlocks, bow, stern, and rowing seats, outside stem and painter ring as standard equipment."
