Manuals seem not to be available from craigcamera.com. I found a few
sites that have different information -- you might be able to cobble
together a manual of your own:

http://www.tlr-cameras.com/Czech/index.html

This last one looks very promising.

Good luck to you in your search -- if the Czechs made cameras as well as
they made motorcycles you have a good camera to enjoy!
