Does anybody here know, what type of mirror that is ?

It is the driver-side automatic version in my 1966 442 and I really need a passenger-side to that.

Maybe someone can identify that model, as the "usual" places only show other types of mirrors and I am sure, that the one on the photo is the original...

Please ignore the dirt on the mirror, it is nearly snowing in Austria and that was the last ride this year, before cleaning and storing away..

Thank you !
