An Ermanox is only worth a lot of money if it's in good condition with it's original lens, and even then only some models with the high speed lenses are valuable.

In reply to Summucron1's comment the lenses on the Ermanox were exceedingly large in comparison to other cameras because of their fast speed f1.8.

This camera looks more like it's designed for use with a microscope or similar instrument, it's too simple to be anything else.
