Alex,
Your canoe was shipped to Albert Frost in Portland, Maine. I have an Old Town Double-End boat that was shipped to Albert Frost in October 1943. In case you have not Googled him I can add a little.
Albert's life long career was with his family business, Albert G. Frost & Son Boat Company in Scarborough, Maine. He later became President and General Manager of Frost Marine Company. The Frost boat business was the oldest Johnson Outboard Motor and Boston Whaler boat dealer and was the second oldest Chris Craft dealer in the United States. He likely bought your canoe for a customer.
Good luck with the restoration.
Jim
