I learned that #83 will be shown in the BMW museum from next year on.
So if you ever come to Munich, make an appointment with the old lady. It's worth the money.

PS: on one wall the standard BMW tool equipment was installed and a set of exhaust pipes hang there.
"Where do these belong to"? "These? They are from Walter Zeller's RS 54" Sure, dumb question.
PPS: thanks Bruce.
