Sorry it has taken me so long to jump in here. My brain has been in a fuzz and my back "went out" (but not for a night on the town) a while back, with what has been going on with Denis... and I haven't checked the board here with consistency.
Basically (and others have said this) all Morris canoes had two pairs of cant ribs until what seems to be about 1905. The two cant-rib-thing helps to provide a date for the canoe, but isn't diagnostic of a Veazie Canoe Company canoe.
What is diagnostic of a Veazie canoe are the presence of the "keyhole" deck-- but only early-on in production, as this deck was replaced with the simple curved deck Morris used on the BN Morris toward the latter years of production (beginning in the early teens)-- this is the deck seen on the Ticonderoga. We see it on the Ticonderoga because that model was born late in the Morris-canoe-game, when that deck had replaced the heart. An "aside" here is that the curved deck is NOT diagnostic of a Ticonderoga-- folks get this mixed up. Wood species for trim is diagnostic of the Ticonderoga (I believe it was spruce-trimmed, not mahogany).
Wood species of the trim can be diagnostic of a Veazie canoe--- "can" being the operative word here, because a person could order a Veazie in mahogany. So, a buyer could order a Veazie in mahogany, pick it up at the factory, scrape off the decal, and you'd have a Morris. No way to tell the difference... except by the serial number.
If you have a low serial number Morris on a rectangular tag on the stem, you have a Veazie Canoe Company canoe. In the database, 6586 is the highest serial number on an oval plate. 6787 is the lowest number on a rectangular plate. So, if a canoe has (for instance) s/n 2345 on a rectangular plate on the stem, even if the canoe is all tricked-out with long mahogany decks, it's a Veazie... Morris used a separate numbering system, unlike Old Town. 1050 is the highest serial number on a Veazie in the database.
I hope this is clearer than mud... my brain is a bit muddied. I know it can be "off-putting" to speak like the final authority on something, and I don't mean to be that way. I've wrapped and un-wrapped my head around this stuff for a few years, and what I've said makes sense to me, based on the canoes in the database.
I've been wanting to comment on the unusual Morris at the Adirondack Museum... s/n 73.60. It has two cants... and it has a s/n with a decimal point-- it isn't 7360, it is 73 point 60... I think because everything about it is different from any other Morris. We'd have to ask Bert (or Charlie) about that too.
Denis is currently "between worlds". I hope there are canoes where he is...
