It's from Bückeburg indeed, but FAKA wasn't located there before 1958
Locked for you!
Thank you for the help!
So it must be an Opel Blitz with a small club-bus like body by
Hermann Harmening KG Fahrzeug- und Karosseriefabrik Bückeburg, better known simply as
Harmening or
HKB.
To be honest I really want this to be finished. And best would be to have another view of it, of course.
So now it´s just hoping and waiting...
