I just got in a 18' sponson canoe for restoration and the owner hasn't a clue how old it is or how it got to his family's camp up Maine. The stems are almost gone and what remains of the serial number has been obscured by a screw. As best as I can make out, it reads 194301 18, 104301 18 or maybe 184301 18. I suspect that the boat has spent its' whole life in Maine, perhaps the Bridgeton area. What can you find out about her for me? Thanks!
