Holster for double trigger Tranter

I have a nice double trigger Tranter that I'd like to get a holster for.

I'm just curious of anybody has seen such a beast, the only one I've found is a basic pouch-with-a-flap but I'd like an open cross draw.

I'm just not sure about how to handle the cocking trigger

Yes, that's what I've figured. There are a few leather workers in various ranges of price and quality that makes holster.
I only wanted to know if anyone has ever seen a dedicated Tranter double-trigger holster or a holster for some other revolver with a fixed trigger guard spur like the Russian Schofields.

Should the cocking trigger be exposed or should it be protected inside the holster is the main question I guess.
