[photo-3d] PUCK STEREO BOX

[pennywise@xxxxxxxxxxxxxx]

H E L P ! ! ! !
I have a PUCK STEREO  box camera with a stuck shutter.
Now, I am quite happy to open the front of the camera and set 
about fixing it - but - before I do that, is there anyone out there who 
has any idea of how the simple box camera shutter operated?
I don't like the idea of going in totally blind - if there is a spring 
missing or a broken one floating loose, I would like some idea of 
what I should be looking for.
I want to use this baby - it seems to be quite well made and I 
understand that the lenses are achromats.
If anyone has seen inside one of these, any advice would be a 
godsend - it is so nice that I am trying to avoid spoiling it, but the 
shutter must work.
Come on kids!!!! thinking caps on.
