I just picked up an Agfa Jsolette, yes I know that J is really supposed to be an I.

I think this is a pre-war model as it has the J and has 2 flaps inside for a 6x4.5 mask along with a little lever to mask the viewfnder for 6x4.5.

Anyhow, I ran roll of film through it and the results were quite pleasing.
I am pretty amazed that a 70 year old camera can still work so well.
