How many "Dux Films" have been released for the "Dux Kino 68", which
was propably mainly sold in Germany late sixties to mid-eighties?
Furthermore, where can I get a list of all ever released titles?
 
I'm not looking for the 35mm stripes for the fifties projector, but
for the ~6cm infinite-loop cartridges in translucent plastic,
containing about 5m of Regual 8mm film (Normal 8). Is its manufacturar
(Dux?) still somehow alive? (Mattel, Hasbro... takeover?)
