Found this model at the recent "Gathering" in Albuquerque, New Mexico. I believe it is the
Silver grey 44b with grey plastic wheels (GPW) 9x24. It is Stannard Type A body. I do not find this model variation (GPW) listed in any of the major reference manuals/sites inc. Nick's. The silver grey model is listed with BPW and SPW but not GPW. I have compared the newly acquired model to my other silver grey models plus the met. mauve models (see pics below) and I believe it is silver grey. I know there are many shade variations of the 44b, but this one is a new one to me. I bought it from a reputable MB Dealer at the convention who had it "stashed" in a big case. Cost was very reasonable.
Sorry the pics aren't better (color variation is more distinct in person), but best I can do right now..........
What do you think??
