At this point I can't do that the boat is not mine. It is part of the collection at the Red Dragon Canoe Club. I am doing a talk 10/18 on the boats in their collection.
I found two more pictures that may help. One has the stem protruding from under the seat (one seat, rear). The other shows one of the thwarts and it is mounted under the inwale.

The stem profile in the first post looks different than the 'repaired' one. The stern is more vertical...I looks like Gould could be a possibility... and even the seat frame construction looks the same as Andre's...
