Put a roll of Kodak T-Max in a Zeiss Ikon Ikonta 520, a compact folding camera dating from about 1930.
The camera is supposed to give 16 6cm*4.5cm images on a roll of 120 film, but the film transport mechanism seems to think it's a 6*9 camera so it only gave 8 images with space inbetween ... and this is the only useable one.
Still it was fun trying and it's satisfying to get a result of any kind from an 80+ year old camera.
