FWIW, I've also got an old Brumberger. It's got three 8x10 shelves and four 5x7 shelves. Unfortunately, the door sticks a bit (it takes some effort to open and often stays up by itself), but otherwise it's nice. Does anybody have suggestions for making the door roll more smoothly? Could it be lubricated somehow? I've been afraid to mess with it lest I end up getting oil on my paper.
I've also gone through two other used paper safes. One, I think a Beseler, had three 8x10 shelves with individual doors. When the door opened, rollers in the drawer pushed out the top sheet. This was handy when using full sheets, but worse than useless when dealing with test strips or odd sizes. Unfortunately, the springs jammed on one drawer and it went from bad to worse -- so bad that I tossed it in the trash. I replaced it with a Premier safe that looks like it was made in the 1970s. The single door pulled down, similar to the door on an oven, but was spring loaded so that it would immediately pop back up when released. It had three 8x10 shelves. Unfortunately, the plastic spring connector in the door broke, making the spring useless. I tried using velcro to get a good solid seal, and that seemed to mostly work, but if the velcro ever gave way, the door would flop down and expose all the paper to whatever the room light is. This made me very nervous, although I never lost paper to such an accident, so I replaced it with the Brumberger.
The new paper safes I've seen on Web retailers' pages seem to be much simpler things than the three I've just described. (I've got one of these and it seems reasonably light-tight, at least for storage over a few days.) If anybody makes anything more complex, I don't know about it or where one might buy it. I've considered custom building something, but for the moment I'm happy with my Brumberger.
