Here are some scans of career service ovals that I promised. First is the Fallschirmdienste officer career service oval. The seven parachute line version was worn from 1968-1986. Here are the three examples in my collection.
The one on the left is original, the one in the middle is questionable, the one on the right is a clear copy. If you look at them you can see subtle differences in color, the shape of the oval and the width of the silver grey oval at the edge.
And here are the backs of these respective ovals:
And here are known copies of the Fallschirmdienste and Fallschirmjäger ovals. According to Walther these were produced in late 1990, early 1991.
Notice how they are almost all uniform in color with the exception of the one on the far right.
And here are the backs, note the light grey color that is the same as the center oval in my photo of the Fallschirmdienste officer career service oval.
