These are samples of the 1980 series in Syria but come direct from Germany. In many colours, black on green is also known and there are several plates of each colour. Some hang on the wall of the Utsch factory in Germany. All have the same number 12-6547. Code 12 is actually for private vehicles and therefore all should be black on white. There are other small differences with these sample plates from the real ones. At least 15 mint plates are known in all sorts of colours with this number.
Most of these sample colours were never used on plates that were in Syria.
