After more than 30 years in the garage, I am looking to restore an old wood and canvas canoe. As I started to get familiar with everything that’s going on with the canoe, I noticed a serial number hang-stamped into the flor center board under the backseat. It is: 1108536 16 or 1L08536 16. The canoe is 16 feet long so I suspect that’s what the 16 is. Does anyone have an idea where I could look-up the number. I also noticed that the bolts on the gunnels are diamond-shaped. There are brass tip protectors on both ends. Thanks.
