I wonder if we could get him to post some more pics...especially of the barrel...

[sarcasm mode 'on']
I have to admit - someone puts a lot of time & effort into these 16"/24" barrels...It would take me a couple hours to figure out just the math/angle and even then I'd do a test on a piece of old pipe before I'd try a full-length barrel...
Only 72 of them made, hmmmm??? Where did that number come from???...
Heh...A Luger Buntline...(or Buntline Luger)...
I tell you what...These guys with their 16" barrel Lugers have got me interested...If I can find a Numrich 16" barrel, I'll do one...
