Curiosity got the best of me - a quick online check turned up this nice snap of KCS E7 #12 with portholes instead of the rectangular windows on the bulk of E7 production:
I checked it out. Nice “snag”. So another porthole addition to go with the MP T&P. Probably the reason KCS wasn’t offered previously.
