Benson, here is the info you requested. Sorry it has taken me so long to put this together.
As with all of our restorations, this one was for a private customer so it is not for sale. It is a canoe that has been in his family since purchased new. There was no logo on the deck or evidence of a plaque. The serial number is 431. It is 17 feet long. I was able to consult with a former owner of a verified Robertson/Old Town canoe that had an original logo on the deck that predated 431 by a few canoes. Both canoes shared similarities.
Some distinguishing features of 431 are:
-The decks are very telling.
-The planking was close to 4 inches wide, white cedar and nearly all vertical grain.
-The planking pattern was far from resembling any sort of pattern I would expect to see on an Old Town. The goring was formed by two planks; a nearly full width plank that was hardly tapered and a very narrow plank that was highly tapered, almost wedged like. This type of small wedged like shim plank in the goring can be seen on a very high percentage of Robertson and Charles river builders.
-Ribs were mostly vertical grain too.
-Spruce inner and outer gunwales and cap rails too.
-Mahogany seats, thwarts, and decks
-The planking was notched into the upper part of the stem and the ends of the rails like Charles river canoes.
-Screws were iron
-Seats were mortise and tennon construction.
-The dimensions of the seats and caned area on the seats were somewhat like those of Robertson canoes I have seen; the stern seat had a larger caned area than then bow seat. The overall width and length of the caned area on both seats had odd dimensions that I would expect to see on Robertson and other Charles river area canoes.
-The ends of the gunwales ran past the outer face of the stem.
-The inner rails measured 13/16 thick by 15/16 wide. They had no bevel on the outside face to compensate for the tumblehome. Both the thickness and width tapered toward the ends as the sheer rose. I would expect to see these inner rail features on Robertson and other Charles River canoes, particularly the width and thickness of the inner rails.
The overall feel of the canoe, the way it was built, had a Robertson/Charles River feel to it yet the shape of the hull and its proportions was very Maine. You could clearly tell the lines of the hull related to the bark canoes of Maine. The turn of the bilge, the tumblehome, the stem profile, etc. Obviously some of this is not factual detail, it stems more from emotion but I don’t think it should be ignored.
