I was just wondering if the driver code or tire thickness of KTM built models (MG, USH, WS, PSC) changed over the years? I kinda thought the MG and USH locos were built with wider driver/tires (.172) than maybe the later WS and PSC models.
Secondly, when did KTM start installing can motors rather than open frame?
Third, were KTM can motors really Pittmans in disguise or actually a Japanese built motor?
Fourth, where would a KTM can motor, model RH-4462S, fit into the genesis of power (USH, WS, PSC) installed in KTM models?
Last, when measuring drivers and wheels to learn the code, do you include the entire width including the flange or just the tread?
