What more can you say about them? There are a couple good Webley holster repros already on the market, and at great prices, too. You can get one from IMA or Sportsmans' for around $30-$40 last I recall. What's the price on this holster and what makes it a better buy than the others?
...or just buying a genuine one. There are lots of WWI and WWII ones that go on ebay. I've picked up a couple for around the $40 mark in good condition.
