Any Copal should still function, though it might be a good idea to exercise it first. Refer to the Shackelton (spelling?) expedition to see large format in Antarctica. Probably the worst things to deal with would be static and wind. I would worry more about newer style bellows cracking than having shutter problems.

I always hire a personal trainer to work with my shutters before heading out in the cold. Three sets of 10@1/2 second followed by 3 sets of 10@ 1 second.
In really extreme cold, you should ensure that there is NO lubricant of any kind inside the shutter. Run it dry and accept any resulting wear; it's the lubricants that congeal in the cold and slow things down.
In the seventies the Australian Antarctic cameras that I saw. (I shared a house with an expedition member) had their Nikon shutters on their F cameras, cleaned of lubricant.
I believe that their LF cameras, (some were down there then) used Ilex shutters as they apparently are a dry, or non lubricated shutter, normally.

I've never bothered with any of that and never had a problem. I've photographed down to about -42c and I can tell you, I eventually start to slow down and freeze up before the camera does...
(btw - the modern fabric type bellows found on Canhams, Phillips or from Camera Bellows, + the plasticy looking ones from Toyo do just fine. I've seen other modern bellows crack, and leather ones - usually because of the dressing/treatments get as stiff as hell. I've also had film shatter into a thousand pieces then I put the darkslide back in...)
