These cameras, in good condition, change hands for about $50US on the eBay auction site, there seems to be quite a lot of collectors after a "full set" of all colours.(posted 8435 days ago)To open it, release the two obvious latches, then extract the film wind knob about 1/4", the camera should then slide apart. If it doesn't open easily, it's probable the cardboard body has distorted, unfortunately not uncommon on this type of camera.
