Hi Paul-- sorry it took me so long to get to this...
Old Town 164232 is a 16 foot CS grade Yankee model, fitted with a keel and painted orange. It was shipped to W.L. Masters and Son of Chicago on June 17, 1957.
I've attached the scan of the record below. Scans of approximately 210,000 records were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. Additional information about the project to preserve these records is available at http://www.wcha.org/ot_records/ if you want more details.
I know you're a WCHA member, but I don't know that I know if you'll be at the Assembly in July... if you'll be there, will you be taking a canoe?
