I found 3 old 120 rolls in the attic when I started the first part of my house refurb.
One disintegrated when I tried to roll it on to a reel, one the markings on the backing paper showed up on the developed film, the third turned out perfect.
I believe they are the previous owner's son in the boyscouts at the weather bureau.
Kinda neat. Once I can print them I'll see about getting them to the son.
