The DSO number for this car is 57-0131. Perhaps I never realized it, but the first 2 digits of the DSO have their own meaning. The first digit is the REGION (geographically), and the second digit is the DISTRICT within the REGION. The last four digits are the Special Order Number, which we knew. I was unaware of the differentiation on the first two digits.
