If you post your location, I'm sure we can find someone near you who has experience with very old film, and they can process it for you. If there's anything there, you can have it printed. Just don't have it processed normally. If you are lucky it will be really curly, slightly fogged, and will have lost a lot of sensitivity. Unlucky, you've got nothing. But you might make your granny really happy.
Good luck. It's a pretty good camera, just not that easy to use. Of course as a mechanic you will enjoy something understandable and menu-free. No batteries! What a concept!
