Hi
It was Westfalia that had that format of model
Between 1951 and August 1958 approximately 1000 Camper Box conversions were made by Westfalia the official Volkswagen Camper conversion coachbuilder. In August 1958 the SO models were introduced. SO is short for "Sonderausführung", meaning Special Model. [1].
Westfalia special models included the SO-23; the SO-34, SO-35, SO-33, SO-42, SO-44 and SO-45. |
