Hello Norm - nothing important, but I was interested to see the build sheet for your canoe, because my canoe is 173693, just 99 after yours. It was shipped May 20, 1964, about 28 days after yours. And the most fun is that I purchased it from Jannell Motors in Weymouth, the same place yours was shipped to. Mine is still 100% original in every way, and still going strong. Have fun with yours! Al
