Some late-period Morris canoes with long decks have the serial number plate attached to the frame of the bow seat. In picture #5, is that a s/n plate on the left side of the seat frame? Otherwise, it would be on the bow stem. If the seats are in fact replacements, then the s/n tag may be lost, but the canoe would likely be circa 1915-20. And if you can make it to the Annual Assembly this year, with the canoe, you'd likely learn more about it. If you can't make it to the Assembly in the Adirondacks, the Upper Great Lakes Regional Assembly will be held in downstate MI this year-- August 15-16. I'll be there, and will still be stoked from having attended the Annual Assembly and would share any newly-gleaned Morris info. I'll also be at the Jag Lake event, near Boulder Junction, Wisconsin, September 17-21. Will have a supply of the Morris book at all these events, if you haven't purchased a copy by then (all profits to the WCHA). It's always a thrill to add another Morris to the database!
The other canoe brands with Morris-type splayed stems are the Rhinelander and some Kennebecs. Rhinelander stems are hardwood-- Kennebec splayed stems are usually cedar. The son of the last owner of Rhinelander Boat and Canoe attended the Jag Lake outing a couple years ago and brought with him the very last canoe that came off a form before the factory closed. It very closely resembled a Morris-- even with the curved short deck of the later Morrises-- only the stem was ash and the seat had sheet cane. I believe the canoe dated to the late 1940s.
