The Volkswagen 411 Tow Hook was made in Germany by Perohaus.
The mounting is very easy. Just put the hook between the bumper and bumper bracket, then lead the screw through the existing hole and secure it with the bolt.
By the way, the nickname of the VW 411 is “Nasenbaer” (coati). Below are pictures of a new old stock Perohaus tow hook.
