MADE IN || WEST GERMANY, no manufacturer on disc.
These are the only two disc variations that I am aware of.
Front cover of the eight-page booklet
Page seven states "Manufactured by PolyGram in Hanover,
Printed in West Germany"
Rear tray insert "Printed in West Germany." with barcode.
The only rear inlay for the West German target pressing.
"9 23774-2" is printed on the reverse.
Notes: This disc is not terribly hard to find.
Jewel case info: Eight-prong disc tray embossed "Patents pending 31"
