This reply has no real contribution the OP. I don't know. No idea. Never read the histories of the Texas Rangers. However:
I did once visit the Texas Rangers Museum. Well worth the visit. Some of the most incredible presentation Colt 1911s you'll ever see. the 1911s were presented to out-going Captains upon retirement. Fabulously crafted and hand tooled gun belts, holster and mag pouches. Most are double rigs in the Buscadero style. Also on display are some of the finest presentation saddles on the planet. Tooling to match the guns belts.
If you make the visit, I strongly suggest you include a roll of paper towels. Your gonna drool all over the floor, the hand rails, the carpets and just generally make a mess
