I am looking for some advice as to what was included in the burgundy owner’s wallet upon delivery of a new car in 1972 (RoW / Austria), apart from the pflegepass, driver’s manual and service centre directory, all of which I have.

My car has a Blaupunkt Frankfurt radio (AM/FM/SW/LW) and I’m wondering whether there would have been a manual for this provided in the wallet? If so, what did it look like (pictures please!) as I need to find one.

Would anything else have been included?

Thanks.
