Any Threepersons (Lawrence 120) style is right at home on a pants belt and the Austin is a great gun belt rig IMHO. Either of those models are timeless and both have their roots from the same general ideas of quick access and minimal coverage.
I love the Threepersons on a 1 3/4" trouser belt. EPS is a great name and has been around forever but take a look at what Rob Leahy and "Reuben J. Cogburn" (AK Leather works) are doing with the 120 style. Mike Barranti also comes to mind but his work is in a class of it's own and will take a bit longer but be well worth the wait.
A Lawrence would be the correct Vintage Rig if you are looking for that period and a tiemless cvlassic, I just think the new leather makers out there do a better job and make a sturdier rig that will last as long as the gun will.
