IIRC you have a camera that takes Lenticulars (The Loreo?). Is that correct? I have a link somewhere for that, I can't find it right now, but you can start here:
stereoscopy.com (

Try this link...
http://www.stereoscopy.com/
...which seems to be what the original poster intended.
Their FAQ has a sub-section called "services". Look here, and there appear to be quite a number of options available (or hopefully still available)...

This sub-sub-section in particular might be helpful...
Processing Old Films
If you find an old camera in your grandfather's attic which still has an exposed film inside the camera, chances aren't too bad that the film can still be developed - even after more than 25 years.
Film manufacturing companies regularly change their film formats and chemical processes - but a few dedicated companies still offer (almost) every process out there. While we don't endorse any specific company, you may want to try to get in touch with the following:
Rocky Mountain Film Lab

Please note, there are also other options (vendors) listed in the "services" section link provided above, so I'm not specifically suggesting just this one vendor I've posted info about. (I've no experience with any of these vendors.) But based on the info at this one vendor's web-site (and a pretty extensive FAQ there), they look like a pretty good place to start.
