Thank you Curt and Chuck,
I, as I stated, do not consider this productive effort but busy work to fill my days. And yes I realize that the information on the side of a toy is not what any purist would deem historically accurate. This is particularly evident with Lionel cars as the date is the date the model was created. K-line and Atlas, with the latter may being more accurate, are to some degree more realistic as the year portion of the date is representative of when the prototype may have traveled the railways. Again busy work but I was hoping that a site would be suggested that described the various types of trucks would be discussed or if there was a difinitive explanation for the Manufacturer's Type.
