I purchased some old expired 120 film with the oldest roll vintage 1972. I slit the film for my Kodak Flash Bantam and took it out for a walk today. A couple from that roll.
My slitter will take the middle section of the roll so the backing paper has the numbers for 6x6 ( 1-12 ). I got 11 images using the numbers on the backing paper. I was pleasantly surprised with the results for almost 50 year old film.
hmmm..just noticed the images are softer from Flickr than what is on my laptop. The lens is actually pretty good on this camera.
If you can adjust your slitter to center the 6x4.5 (16-on) framing track on the final strip, you can get 16 on the roll. Nice to see these old cameras still at it. I need to fix a sticky shutter on my Bantam RF.
