Trying to Id any information on canoe with this number. Suspected to be a Chestnut but unsure, thought to be from 1940, possibly earlier. If it’s a Chestnut I’m wondering if it’s a Guide, or maybe a Prospector, although it seems too narrow for that, but maybe not deep enough for a Guide, but I also know Chestnuts have somr significant variability. No decal or papers, thanks for any help!
