MADE IN || WEST GERMANY (no manufacturer on disc)
These are the only three disc variations that I am aware of.
front cover of the six-page foldout booklet
Page five states, "Manufactured by PolyGram in Hanover, West Germany." in script
followed by "Printed in West Germany" in a typewriter font.
Rear tray insert, "Printed in West Germany" with barcode.
It's really hard to see so here is an enlargement:
Only tray inlay known to contain this target disc.
"80035-2" is printed on the reverse.
Notes: This disc is fairly common.
Jewel case info: (POLYGRAM with mirror band) smooth frosted two-dimple, nothing embossed on the back.
"22" is embossed on one tab and "11" is embossed on the back portion, inside bottom center.
Eight-prong disc tray embossed "Patents pending 13"
