Rear axes look like those of the former pickets I've seen before. Also notice the extra horizontal bracket on the clutch pedal: all the former pickets I've seen had something like that on the clutch and break pedals, as that was part of the system used to reverse the operator platform.
As said, look at the SN suffix, as if it was a picker it should be marked.
