OT 86407 is a 16 foot CS (you're right!) grade Yankee model with Western red cedar planking, open spruce wales, oak decks, and a keel-- painted light green and shipped April 13, 1925 to Crawford County, PA. There's a note on the back of the record (possibly an inquiry) dated 6/4/75 from Lewis Grigsley-- scans are attached 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/catalogs/old-town/records/ if you want more details. Glad you're a member of WCHA as that enables us to do this sort of work.
