Hazard switch / relay - help me identify it. From a Fintail

[ScooterABC]

I removed this hazard switch / relay from a Euro Fintail at the junkyard.

Bosch part number 0 336 851 004
Supposedly the corresponding Mercedes part number is A 001 544 7132

The socket/plug arrangement looks way too new for a 1966 car, and all of the google reference I find to this relay are in the European market.

As an example, I can buy this part new on Amazon UK, but I can't find it anywhere in the US.

Thoughts?

A better photo would be of the socket layout with the white plug removed. The numbers of each pin on the switch, and their layout, would also help to identify any interchangeable part.

Here's a stock photo, but you get the idea of what type of pins are involved...
