.38 Turned Alum Snap Cap

I’ve had this item for awhile and don’t know much about it. It seems to be a solid turned aluminum 38 Special snap cap. The black portion of the primer appears to be hard plastic or some other hard material. Any thoughts on who made it and when it was made?

This one is a spring loaded snap cap designed and manufactured by Lothar Walther in Germany. Production of this variant started in the mid 80’s.
