I have a 16' longitudinal strip canoe that looks like a Peterborough but there is no plate, stamped number on the stem, or any other identifying marks. I picked it up from a gentleman just before he could fiberglass it. He said it had always been in his family who had a cabin in the 1000 islands on the St.Lawrence and thought it dated back between 1910 and 1920. It does have a chrome ring in the bow for a mast (but no step). The 3rd plank down is mahogany , the rest are cedar with an oak keel. There are supports for original kneeling boards but the previous owner took them out and added cane seats. Any idea how to identify it and who may have made It.
