Magpul decided around 2013 that they wanted to conduct some business in a high-class environment, and elegantly restored a 1952 Flxible to do the job . . .

 

On the inside, Magpul has stocked the cabinet with 1950’s era weaponry. The top row of the cabinet has a line of 1911 handguns, and below that are a slew of Thompson submachine guns

I may have heard of Magpul, but didn't recall what they make or market... it's gun stuff! This must have been on display in Vegas at the SHOT show
