This vintage Hella catalog shows the great Hella searchlight and the rare door hinge bracket for Volkswagen Beetle and T1 Samba.

As you see at the pictures, you have the following options:
Option 1: VW Oval is "VW ganz verchromt, mit Schiffchen Volkswagen PKW"
Option 2: VW Oval door is also "ganz verchromt, Türschanierhalter für VW-PKW".
Option 3: VW T1 Bus is "ganz verchromt Türschanierspiegel für VW Lieferwagen". You can also use the first option if you do not find this for your T1.
