Holy smokes that's a lot of Coves! Really nice fleet. Maybe I can help with the Devinci. Devinci is from Quebec, and extremely popular there, they like to "buy French". Their factory is directly across the road from a mine, the product is 100% Canadian. They build nice aluminum frames, but were known to skimp out on components.
I did read that. All Canadian aluminium. The frame is really nice. It seems to be raw too. There's a bit of corrosion on the seatstay bridge that'll need a wet sand but the rest cleaned up with some autosol and wire wool.
Devinci actually replied to me on IG and said I should email them with the details and they might be able to find something in the records but not heard from them since.
