Exposure-#2 folding pocket Brownie

I have a #2 Folding Pocket Brownie from about 1907-1911, which I would like to use, as it is in perfect order. It only has "Instantaneous" shutter speed (plus bulb, of course) and three exposure settings, marked (wait for it!) 1,2 and 3. Does anyone know what this might correspond to in modern terms, or can you offer me any advice at all on using this lovely looking camera?

Hi, Ross,

Congratulations on having such a wonderful camera. I have a copy of

the Kodaker's Bible, "How to Make Good Pictures", 26th edition, from

1940, and I now quote from it to answer your question: "The markings

1, 2, 3, and 4 on some single lens folding cameras are merely

arbitrary figures though they correspond, roughly, with f.11, f.16,

f.22, and f.32." Hope this helps! So obviously you have a camera

with a "slow" lens, so sunny days and fast film will be your best

bet. Best of luck, and have fun with your "new" camera!
