I had some type 55 film with what I suspected were worn out chemical pods, and I had some type 665 pack film whose pods were just fine, so as an experiment I transplanted the 665 chemical pods onto the type 55. It seemed to work just fine.
My thanks to Arne »
link for the pod swap suggestion.
If you are shooting type 665 and accidentally open the camera and ruin the film, remember that the chemical pods will still work elsewhere!
