Three Rivers Canoe Maker from Maine?

Has anyone ever heard of a "Three Rivers Canoe Maker" from Maine? There is a sign advertising their name with "Birch bark - Canvas" up for auction on March 27th at https://www.auctionzip.com/auction-lot/lot_11C4887A58 in South Paris, Maine. The list of Maine Canoe Builders at http://wcha.org/catalogs/maine-list.htm doesn't include them and I've not found any other reference to an early Maine canoe builder using this name. The messages at http://www.wcha.org/forums/index.php?threads/834/ reference two modern builders using this name in Canada and South Carolina but I suspect that neither of them worked in birch bark. This sign may be a fake but it looks old. Has anyone else ever heard of this company and can you provide any more details? Joseph Ranco is the only canoe builder I know who is documented to have worked in both birch bark and canvas. See http://www.wcha.org/forums/index.php?attachments/39942/ from 1888 for more about this. I will not be bidding on this sign. Thanks,

Benson

 

There appear to be many locations in Maine with a three river designation. The Milo area has that name as described at https://en.wikipedia.org/wiki/Milo,_Maine and many canoe builders have worked in that region over the years. The Forks and Millinocket both have Three Rivers Whitewater as the page at https://threeriverswhitewater.com/ describes. Waterville, Farmington, Alfred, and Anson also have claims to this name. It appears that any significant intersection of rivers can use this and there are many available.

Pittsburg is not normally associated with old birch bark or canvas canoe builders but I suppose that anything is possible.
