Heiser made a fair number of lined holsters. The best (in my opinion) are the shearlings, sheep hide if you must, lined. The outer and structural parts of the holster are cowhide, usually tooled. But the sewn in lining is the sheep skin cut short. Pretty nice, but very scarce.

I've seen but didn't buy a swede lined holster. The reason for not buying it was it wasn't for a gun I owned. My collecting needs to be for useful items.
