EH has been out of business for about ten years. I bought two new-in-bag Fas Tracs, about three years ago, and they are very well-made rigs. Mine are for 5" and 6" 1911s, and I can get you the part numbers off those. Someone must have a catalog, from the day. There are a bunch of EH holsters on ebay right now, and there may be some info there.
