There was another outfit located somewhere in Eastern West Virginia, probably Martinsburg, that also made some variations on Lee-Enfields, both in .303 and 7.62. There was a "tanker" variation, a Jungle Carbine replica (which didn't have the adjustable sights, just the battle sights) and a couple of other variations. I had one of the Jungle Carbine replicas and also had an original Jungle Carbine. The finish was pretty good on their products but some of the their things took getting used to, but I've never cared for the Ishipore variation anyway. Anyway, there was a .45-70 carbine but I never saw one. I think I saw most of the others. The Tristar rifles look better, at least in the illustrations.
But they are either no longer in business or just don't make the Lee-Enfield variations. It might be that the supply of original Lee-Enfields dried up.
OK, this just in. It was the Gibbs Rifle Company but they have evidently gone away. However, the practice of offering modified Lee-Enfields, usually sporterized, goes back to as far as WWI, and such things were also done to Mausers, Krags, Mosin-Nagants, and even Lebels. The pre-war Shooter's Bible devoted a few pages to sporterized military rifles. The current thing of creating what are basically different military models is something new, however, and is more like producing experimental rifles.
