There is a company in Europe making them.

That Thai gent who makes Crosman/Benjamin lever breeches also does laminate stocks:

The inletting, as I have seen on his pistol grips, are quite rough though and not Vernon Austin quality :)
This is the German site Mr. Retat was referring to:

The Thai shoulder stock is around $250 shipped, IIRIC.
