Todd, OLD SAFES were -burglar proof- (some at least) meaning the door fit tight, so you could NOT pour nitro down the crack and blow the door off...thats a TIGHTER than what you get now fit...
put a small pressure cooker on your stove, block the vent off, and turn the fire on.... what happens? IT EXPLODES...
OLD safes, the dial was brass as well, not the plastic crap used now, or the zamack (sp) used now... SOME I have seen have the rod down the dial hole made such that it will NOT leave much of an air gap...they were designed to NOT be able to be driven in, in fact... Star comes to mind on 1...makes another pretty air tight fit..
