Just received this original (not a photocopy) Photofact, in mint condition. Twelve pages of schematics, parts lists & cross references, and tuner alignment instructions for this "tuber" radio and power chassis.
The Sams number is Set 397 Folder 5, dated May 1958. Attached is a partial scan of the front page.
Unfortunately this is for a radio a couple generations older than what I wanted for daBenz, which has the solid state Europa MU radio. Have $14 invested, will sell for $15 (to cover postage). Send me a Private Message if interested.
