I got a new ( new to me ) finder for my RZ67. As I was digging through my refrigerator for a roll of film to try it out with, I ran across a lowly roll of Plus-X in 120 hiding in the back. Plus-X used to be my favorite B&W film before it went away. Don't want to burn just doing test shots. Found I was out of B&W in 120. Ordered some FP4+ ( my current B&W goto film ) and some Arista EDU to try. Think I will hold out on the Plus-X until I have something purposeful to shot. It expired in 2002, but I'm sure it's still just fine. I've shot slide film older than that with no issue.
