37 heater control valve location

Anyone have a picture of this type control valve on engine hooked up? I rebuilt this one and can't find any info on it in the manual.

I've got one on my '47. I suspect this type was introduced in '41 or so. The earlier ones were strictly manual ... you opened a valve like that on the drain petcocks. This later one of course uses a cable.
