Hi Jim,
I am not sure if you are aware of this, but the gray plastic handle grip cover did not first show up until midway into the 512 run.
Hence, models 508, 509, 510 and 511 may have had primarily gray trim, but all have had the 505's black grip originally throughout their run.
The very first 512s that had the earlier black grips from the factory also had a gray-painted composite front axle, because of material shortages related to the Korean War.
That is information according to David O. (odavid123)
