Cabelas sold some 1A's in .30-40's with Circassian wood, which is probably one of the more common variants. I have one and the wood is pretty yummy
Cabelas Gun Library sometimes has some interesting variants
The Boddington series had a 7x57 in the 1A, and there are a couple of them on GB right now.
I have heard of over-runs with standard models, that turn up with Circassian wood, they are doubtless future rare. PM ElNumeroUno as he either knows of or has some available.
