Following on from my recent Secret Sam post about the camera, Bill's comment about the actual film format got me thinking about the inside of the toy camera. I don't have one any more so I can't post a picture. I seem to recall a metal spool inside.
Anyways, here's a picture of the camera spool dial courtesy of one for sale on Etsy:
Bill's thinking is that the film spool was a 127 film like this - courtesy of Wiki [Smial]. The 127 roll film with empty reel is in the centre, a miniature cartridge 135 (left) and a 120 roll to the right for comparison:
Looking for answers I went to the funny papers paperwork that came with the Secret Sam toy from Topper Toys [my own collection]:
With the camera prominent on these toy papers, especially the case sleeve above, which even shows an example of a photograph, the camera film IS mentioned and it is indeed a 127 roll! Way to go Bill our resident camera expert!
