Writing on another site (involved film rescue and the photos captured on old never developed film from WW2) where the guy used a portable canister developing device, like one I used to have in the early 60's, and then I got nostalgic about my first 35mm camera:
I used this camera on 6 week vacation to France and environs and loved that it fit in my pocket. I also had a trigger cord to screw in the shutter button.
Only used B&W film in it and developed it in a canister that would load two films at once.
It was a big step from the Brownie Box camera that preceded it. I remember walking home from the camera store taking random pictures of trees and buildings.
Enjoy
