What would be phase I if the Bessemer are Phase II and III?
I am not familiarwith the Phase III and IV SD9s. This may be a newer deinition since I last paid much attention.
I have always condidered the 4 radiator fan with external cooling pipe to be Phase I and the Phase II to have the 2 larger radiator fans like the SD18s. Of course the DM&IR also had high hood SD18s.
i'll look through my info regarding the stenciling....
