When the PRR started to update the K4s, they also changed the style of headlight and mounting location in addition to the new cast pilot. There are also many minor changes.   If you google PRR steam engines you find a number of sites with pictures.

thank you for the information

Hi I was just wondering what the difference is between the pre and post war versions of the
Spectrum K4 pacific other than the pilot? Ie is it okay to run the different versions together on one layout without them seeming out of place?
