MADE IN || WEST GERMANY, no manufacturer on disc.
These are the only two disc variations that I am aware of.
Thanks to Keith Hirsch for this scan.

front cover of the booklet

It's hard to read on the dark blue background but the rear tray insert says "Printed in West Germany" with no UPC.
Only back inlay known to contain this target disc.
Later non-targets tend to come with barcodes.

Notes: This disc is not easy to find. Expect to be searching for some time.
