I have a Seroco (Conley) 5X7 camera with a Wollensak shutter dated 1910.
The apertures are marked as . 8 16 32 64 . 256
Can anyone confirm that these are marked using the US system for apertures verses the later f/ system?
Also, is the first dot used to indicate 4 and the second dot a 128?
I attached an image of the shutter with this post to assist.
Thanks for the help.
