Unfortunately, our canoe is 300 miles from here, so I am asking a question about it from memory. We bought over 40 years ago and it was elderly at the time, but I have never tried to check to see how old it actually is. It's a canvas and wood 18' model that looks like ads for the Otca in the "100 Years" book. I asked the man where it is stored to look at the serial and he came back with ROS46888 on the stern centerline rib and 46888 marked on the bow centerline. Any help on a date would be much appreciated.
