Guy in fort worth was Casey, think he worked for Sunbelt.
I've bought the last 12 tank ends he has gotten in. The good ones make great blinds but be very careful to make sure to check closely for leaks. I've got 2 that may turn out to be unuseable. Fuel has saturated the membrane between layers of the tank and the smell hasn't cleared out in several weeks since being built. The last 5 I got from him are in much better shape and don't appear to have ever leaked.
