Hi! New to the community here and hoping to get some tips on this camera I picked up. It is a Kodak “No. 3 Folding Pocket Kodak Model A” according to the film back. The lens says “Carl Zeiss Jena No 48294 Protar 1:8 F=136mm D.R.P. 56109”. I would like to figure out how to use it but I cannot find much info anywhere about it. The most confusing part is that the aperture goes from 17-12-8-6-4-3 with dots in between but the larger numbers are wider than the smaller ones. Any help or comments are appreciated!
