Welcome, Christine
Old Town 169577 is a 16 foot Otca model, constructed between December of 1959 and April 1960. It was fitted with a regular keel and full length bang plate and additional bilge keels (these would be on either side of the main keel-- usually applied to help protect the bottom of the boat and often used on camp boats or livery canoes). It was painted design #4, which is a favorite of many! The canoe was shipped to Floyd Johnson's Radio and SG in Joliet, Illinois, on April 6, 1960. The back of the card notes an inquiry by Myron Cromholla on 10/3/75.
A scan of this record is attached below, including a scan of the information on the back. If this doesn't match your canoe, we can try again. The microfilms and scans of these records were created with substantial grants from the Wooden Canoe Heritage Association (WCHA). I hope that you will join or contribute to the WCHA so that services like this can continue. See

Wonderful that it's a family canoe! Is the original design intact? You may want to use the "search" function above to find interesting information in the archives regarding design #4 and the Old Town Otca post-1957. Searches using "design #4" and "Otca Yankee" may bring up the information I'm thinking of. I'll poke around and see if that's the case-- don't want to misdirect you.
