Hey Yoko, that Rank looked a lot like a Yashica rangefinder. I wonder if they were rebadged. Just bear in mind that some cameras won't work without film in and appear "dead". Not many do this though. Will be doing the car boot run again this coming weekend.
Tried a sunset shot with the Polaroid and Impossible film last night, takes some getting used to as the film is on 160 iso.
