That lump is a hydrostatic lubricator. If nothing else it provides a "lump" as you so poetically put it in a corner of the cab which adds to the general clutter although the third photo below shows that I've located it upside down. Nevertheless it looks to be the correct pattern, or very nearly so.
These three are the only photos I have of a backhead for the K. The only one which is really clear is the one for 1913 which is far too early for my needs. The others seem to indicate the locations of various components, although neither are too clear.
They all seem to indicate that the water gauges are about right for my model, although I'll spend a bit more time reviewing these. Nevertheless I suspect that the apparent difference in levels for the various control wheels and the water gauges is a matter of perspective rather than true location.
And I've just found my GA which includes the backhead. Why did I not refer to it before? Because it's the loco as built in 1913. It's rather unclear and needs the photos as clarification. The washout plugs on the backhead I've made are indeed rather low, but it confirms that the top mounting for the water gauges is slightly above the level of the regulator stuffing box - at least in 1913.
In short, I'm sticking where I am as the nearest interpretation I'm likely to achieve.
