Old Town 150309 is a 17 foot CS ("common sense") grade Otca model canoe finished between February and June of 1948. It has red Western cedar planking, open spruce gunwales, half-ribs, a keel and outside stems. Painted dark (?-- hard to read) green, it was shipped to Fort Worth, Texas, on July 12, 1951.
There are enough details here for you to determine if this is your canoe--sounds very nice! Love those outside stems and half ribs on a CS grade canoe!
At this point, I'd be telling you that your scan is attached, but my computer has crashed again (I will not name-names, but it's a four-letter word beginning with a "D" and ending with an "L"). I do have a backup comp but will need to install something to convert the file before I can upload it.... so, it'll be available for you eventually.
If someone else with the OT CDs gets to this thread before I've posted the build record, it's scan number 00695A.
Does your canoe need any work? I hope you know we love pictures....
