I've been collecting radios over the years, and should know more about them. I have a good idea on what I think is the oldest,
the blaupunkt A253...

The Essen, I'm guessing 60's

The Frankfurt I have two faceplates for.... I'm guessing mid 50's?


The Koblenz...?

And I think this is an early Telfunken body... but there's no id on it...

Any ideas on helping to ID these better? (the early blaupunkts I have power packs for but not sure if they work)
