F C Meikai - informations, please

Hello
I’m looking for all the information concerning the F C Meikai fixed-lens zone focusing camera
http://public.fotki.com/BlueWind/meikai-fc-camera/meikaifc.html
I’m only interested in this model, I already have information about other models from the Tougodo Company.
This F C Meikai is usually classified as a junk-store camera, but apart some lightleaks it performs surprisingly well for its kind

Thank you in advance for any input
