With apologies to the OP, jeeps, ... I hope I'm not hi-jacking your thread, but I find this topic of the Threpersons holster fascinating. Also, just like your Government Model, my Commander is in 38 Super. Quite a coincidence, as this seems to be a much under appreciated caliber, even though there were many Texas Rangers and other early Lawmwn who appreciated the cartridge!!
For Red: Here is what I guess you call the welt. It seems to be two layers of thick leather, and the holster seems to be both robust and delicate, if you know what I mean. I was quite amazed at the workmanship and minimalist look to it. The lining seems to be something like soft glove leather.
Best Regards, Les
