Exposing [really] old B&W films

[htmlguru4242]

I've been browsing around on EBay, and I've noticed a large number of very old, unexposed films being sold. Many of them are from the 1950s and 1960s. I kno that some people would use these as collectors items, but is there any chance that they'd still be useable??

If they are slow films, they might not be too bad. The faster the film, the higher the base fog, and the less it's worth bothering.

I've tried exposing a glass plate I found in a plate holder. I exposed it at EI 6, and got an image of sorts. But the emulsion was full of bubbles and fungus spots when I developed it

I have a pack of 2 1/4x 3 1/4 Ansco sheet film in my freezer. Expiration date was 1945. I've been trying to decide whether to bother with trying it out. Says to use type 47 developer - I guess I could mix some up.
