Here's a slide I found at my Dad's house that shows Soo 1027 at an unrecorded location. In color no less.
Formerly Monon 510, there are quite a few changes the SOO has wrought on her appearance:
Added Worthington SA Feedwater Heater, relocated the power reverse cylinder, replaced the tank (or "tender" if you prefer) and stack, relocated air pumps to the pilot, relocated headlight (yuck), and a new cab.
