Never say never...
Gotta be Morris. The splayed stem, gunwale cap profile, keel fastened at every rib- all point to Morris. While Brodbeck (and Nutting and some Robertsons) do have some similarities in shape and construction, the Morris canoes are distinctly different from Charles River canoes in many ways. That stem is an immediate giveaway. Charles River canoe stems are generally square in cross section with the edges and amidships end of the stem chamfered.
One more thing not apparent in your photos are the tapered ribs- narrowing significantly from keel to gunwale. Many of the Charles River canoes were made with un-tapered ribs, while Morris ribs were dramatically and elegantly tapered. Finally, the floor rack looks original- Morris used narrow parallel longitudinal members attached to each other with wider cross-pieces. Your photos don't show the ends of the floor rack, but each of the longitudinal members should be rounded to a circular profile when viewed from the top.
All this said, there are always exceptions to the norm. Coincidentally, just today I brought home a "new" Morris canoe nearly identical to yours (Model A, Type 1, closed gunwales). This canoe is in near perfect original condition- no cracks, breaks or rot, original finish, original canvas, lightly used, etc. It is definitely Morris as evidenced by the intact and clear deck decal, but it defies one of the defining characteristics of Morris- the keel is attached at every other rib. The canoe has not been re-canvassed, and there are no screw holes in the alternate ribs, so this canoe was built with keel screws in every other rib.
Regarding price, your canoe was a bargain! I am extremely happy to have paid a similar price. An original Morris in unrestored good condition is a rare find (no slight intended against other fine original canoes from other makers). Restoration- in whatever sense the word is used- means that one less original canoe exists. Thus, every day these nice original ones become rarer. A wonderful find indeed!
