I have no idea if these were marked - yours is the first (probable) King that I have known of. Acme, who built similar boats were marked with a stencil. I don't recall where, but may be able to look at one when I am the Antique Boat Show in Clayton, NY next week.
Out your way, there is the Columbia River Maritime Museum in Astoria, OR, the Center for Wooden Boats in Seattle and the Foss Marine Museum in Tacoma. Transportation notwithstanding, I can say with confidence that the Wisconsin Canoe Heritage Museum would be interested in it.
I doubt this is something that could be restored. Given its apparent condition and age, preservation is probably the best goal.
