saw this on arf.com The following is a copy of what the owner posted about it (yes, it is a personal collection!!!): If the truth be known; I was fortunate to be first involved with NFA devices many years ago when sex was safe, motorcycles were dangerous and NFA "stuff" was reasonably priced. Indeed my DD and Class 3 goes back to 1978 (was there a 1978??) when one could afford this stuff. Unfortunately, all the NFA "stuff" was crated away in warehouses while I spent years fighting the battles of Corporate America. Only recently have I had the opportunity to design and build a 1600 sq. ft. underground Vault and Gun Room with its own underground firing range. So most (there is only room for half to two-thirds of the "stuff") of it can now be out (well, relatively out, because all displays are inside the underground vault) where it can be seen and appreciated. (All the cabinets you see are full of NFA devices which I'm hoping to cycle through the displays). I didn't mean to be cute with my inquiry regarding the 1927. Yes, it is on the wall right under the fully engraved 1921AC which until recently nobody, apparently, knew about. But, having been out of it for some years now I wanted value opinions from the RKIs on this board so I made the first post in this thread. Again, I really solicit your thoughts, comments and observations. If anyone has questions about the Vault Gun Room I'll try to answer them. ...there is not a single post sample and only a very few pre samples.
