I will post more info and pictures tonight about Fred, the mystery machine (as in Scooby Doo). DD got several good pictures but I will get dimensions too. Glad I have the experts stumped here and thanks for the Karlsruhe, Germany, information. If that series started in 1954, then it probably is and 54 or 55 model because the serial # is PA 070279. Germany would have still been rebuilding after WWII. The Singer name is on the backside of the arm.
