Congrats on the pickup of the Langford. I've got a late '70s 15 footer as well. Will post about that on your other thread.
I'm sure all the knowledgeable people here on the forums will help with your restoration.
By the way, there is a Canadian chapter of the WCHA with most members in Ontario including some folks around the Kingston area. We are planning a bunch of events in 2022 (provided Covid doesn't derail all our in-person plans). You might be able to get some hand-on advice from other Langford owners.
