Can you attach the photos of the numbers from each end? The Old Town with serial number 9875 is 17 feet long so that probably isn't the correct record. The Carletons with numbers 9375 and 9875 are 18 and 15 feet long respectively so they don't match either. The Old Towns with numbers 98754 and 98755 were both 20 feet long. The first one was CS grade with bilge keels and the second was AA grade with lots of mahogany and a floor rack. Are there any signs of extra keels or mahogany on this canoe? Additional pictures might really help in this case.
