Old Town 148512 is a 17 foot CS (common sense, or middle) grade HW model canoe that was completed April-June of 1947. It has red Western cedar planking, open spruce gunwales, and ash decks, thwarts, and seat frames. It was fitted with a keel and painted dark green, then shipped to Minneapolis, MN, on April 25, 1949.
Does it have cane seats or slatted ones? I ask because it seems to me that in 1947 Old Town hadn't re-established their cane supply, but by '49 they should have been able to put in their standard cane seats (which by then consisted of machine-made sheet cane, fit into a groove on the hardwood frame). So, the canoe might have been finished with wartime slatted seats in '47, which were swapped-out when the cane appeared again. Most build records don't specify slatted seats, even if the canoe had slatted seats. I believe the cane supply dried up for all canoe builders in about 1943 and lasted until about 1947.
Is the canoe still in Minneapolis? I ask because that's my ol' hometown.

I replaced the seats with cane when I rebuilt and re canvased the canoe in the late 70's. I recall the original seats were slat. I received the canoe from the original owner, and my guess is, it never left lake Minnetonka. It originally was a sailing canoe, and I have all those parts stored away. I replaced the mast thwart with a straight one, and put a nice portage yoke on it. I wanted a classic beauty for trips through the BWCA and the Superior Quetico. I was a teenager when I rebuilt it, and want to do some more work on it now.
It does continue to live in Minnesota, on Christmas Lake. I live in New Mexico now, so it only gets some TLC when I visit.
