Found these in Hearne, TX. I believe the second one is a langtry, just not sure on the first. I've posted the third one before, but here's a better picture.
I would say the first one a small Ensor or Edgewood. The second probably a Perdiz. No Langtrys in the Hearne area. I can't see the 3rd one good but could be a Yarbrough. Just my opinion.

I'm no expert, but I thought the shoulders of a perdiz dropped down, as opposed to a langtry that went straight out. To me these go straight out. But like I said, I'm no expert.
