As been said it is not clear which forms Kennebec built their Morris-series canoes in 1924-1925.
We do know they listed 291 of these canoes in a serial number range different from their other canoes (50,000-50,289 + 1 unnumbered). They were built in three lengths, so that would be considerable work to build three molds for a short run of canoes. If this is the case, perhaps they expected to build more than these.
On the other hand the simplest answer is usually the best, and that is that some of the original Morris forms survived the fire. Modification of Kennebec forms is also possible - it was done by both Old Town and Chestnut, at the least.
I do note that the OPs canoe has a straight stem, rather than the splayed stem typical of Morris. To further confuse things, Kennebec was known to build canoes with splayed stems that weren't related to Morris.
Fun stuff!
