It will take more than a serial number alone to identify this canoe. Most manufacturers didn't mix letters and digits in their serial numbers. Penn Yan had some that started with a letter C but these usually had one or two more letters before the numbers. Can you provide some pictures of the numbers from each end with the surrounding areas? Some images showing the decks and interior could also be useful, along with a confirmation of the extreme overall length in a straight line. Thanks,
