If you found some old black and white film, maybe you can still use it. I found some rolls of old Kodak Verichrome pan 125 expired in 1972. So I loaded one roll into my Yashica 124G and made some quick test shots.
When you find some old outdated expired black and white film. maybe you can test it out! I found some Verichrome pan 125 in the thrift store for 25cents per roll.

For developing I used the stand developing method with Rodinal dilution 1:100 for 110 Minutes and only agitate the first minute. I was very suprised how good the result was. below you see the result:
