NSU Sport Prinz and NSU Wankel Spider Bonnet Emblems

Description

Set of 2 Bonnet Emblems for NSU automobiles.  I believe these emblems are for the NSU Sport Prinz and also the NSU Wankel.  These may also fit NSU Prinz I, II and III.
Each emblem is a different design.
One appears to be replacement emblem, is metal and unpainted.  Mounting tabs and keepers are present.  The color scheme can be seen on the second emblem.
The second is plastic and mounts on a plastic base.  The photos show the two pieces.  The emblem needs to be glued to the base.
Both of these emblems are hard to find and are in good condition.
