Thanks to everyone for your help. I also found some info at http://www.recguns.com/XIIIB1b.html
, and a list (albeit incomplete) of manufacturers at http://www.gunsgunsguns.com/gunhoo/a.safes.htm
I have two separate applications. In one case I can put in the largest gun safe I can buy. In the other, I have an unusual and limited space, and I'm still trying to find a quality company that will build the right size for us. In each case, to the extent possible, we'll follow the advice to maximize the size of the safe, and include fireproofing as well.
Ringo, one question. I found 'Brown Safe Manufacturing' on the web at http://www.imall.com/stores/brownsafe/
. Is this the same company you refer to as Browning? Whether it is or not, please post the name / contact info on your dealer, and a web site for Browning if it exists.
