I tried a Meikai FC camera (before and after foam seal replacing); this is one of a series of Japanese cameras that were offered to customers at gas stations or sold at toy shops; some of them were made by order from some companies, with their logos, to be distributed as gifts.
I don't know too much about this camera (the maker was a respected camera developer since the thirties, in Japan). Recent models are all-plastic and made in China...
Pictures of the camera and some photos here (before and after repairing the lightleaks). Note: some associated advertisements in this website are noisy, turnig off the sound is recommended
All the information on these cameras is welcome
