Hello alltogether,
First of all, I apologize. I did not explain what this tool is good for. Yes, Cees is right, it is (was) used for the correct installation of the headlight housing.
I would guess it is made of diecast or aluminum.
No Bob, the final bid price was 115 €uros [:0](about 130 - 140 $$) but this was already - as I believed - a little to much for a just "nice to have" item. :?
