St. Lawrence skiff or an early Canoe? Need help

I just salvaged an old skiff or canoe from a camp in the Adirondacks. I can't tell what it is or who manufactured it. The camp was located in St. Lawrence county NY near Canton, but I don't believe this to be a Rushton.

The boat is approx 12' long with painted canvas sides. The removeable bottom boards have brass markers marked with a script "R". There are no other markings or tags on the boat.

Can anyone from WCHA identify this boat?

Thanks,
Shawn
