Возможно это номер рем. завода или автобазы. В любом случае к оригинальному номеру рамы это отношение не имеет.

The AC was not a factory fitted speedometer and would be incorrect for a factory restoration. They were however used in other military vehicles of the time such as the DUKW and were often fitted to the jeep by service personnel as a replacement. The AC was used as a replacement for the non-incremented slat grill speedometers. They are therefore correct for a motor pool class restoration.
