I'm trying to find information on this round chrome horn ring for a 66/67 Type 1. From what I understand it was made by Vereinigte Deutsche Metallwerke VDM which was a German company. If anyone has any information that would be great. Is there a VDM catalog with a picture of this Full circle horn ring?

Never seen one before! The car is pretty loaded in that pic, there's air con, trip speedo, A-post and door scuff guards, air vent trims...Oh, and a steering wheel cover.
