Yes, but I was questioning the opening in the jacket over the hatch.

Gordon - 

You’re not talking about the hatch that gave access to the superheater header and the front-end throttle, are you?

There certainly have been good discussions on feedwater heater pumps based on this excellent top view of the 1218, but I'm surprised that no one has questioned the opening in the boiler/smoke box jacket immediately behind the smokestack, obviously giving access to a bolted smoke box cover (Archives drawing NW-C33710).  I say that I'm surprised because I can not see comparable openings in the few suitable views photos of other Class A loco's with jacketed smoke boxes that I have been able to find.  So, this appears to be a modification to 1218 only.  Any thoughts?

The A class engines used a Worthington 6-SA feedwater heater system.  There was a turbine pump under the left side of the cab to provide the cold water and there was a hot water pump under the left running board at its forward end.

All the Js and the Y-6bs used Worthington SA systems.  N&W had hundreds of engines equipped with the earlier Worthington BL feedwater heaters, which appeared under the left running board and incorporated the pump and heater in one casing.  The Worthington systems were very efficient and dependable and, AFAIK, N&W never used feedwater heater systems from any other manufacturer (Elesco, Coffin, etc.) nor did it feel it necessary to build its own.

In this topside view of 1218 can be seen what I assume is the feedwater heater forward of the stack. Was this an in-house design or a product of an outside manufacturer?
