I also have a #3 Box Brownie that shoots 124 - try finding THAT somewhere. I used it for doing wet plate demonstrations, then put it in storage for a while as I wasn't doing wet plate for a long time. Just dug it out yesterday. Remarkably capable little camera for something so simple. I suppose if you wanted to shoot film in it you could always buy 5" rolls and trim them down.
I did some more poking around on my own after posting this - the stops listed in Camerapedia are actually US stops, not f-stops, so it's actually f11,16,22,32. I dropped a roll of PanF in and I'll burn through it at lunchtime. Should get some interesting results out of that simple meniscus lens.
