Well, a little more progress... we now have a heater valve.
One of the nicest aspects of working on members of the Landrover maque is the way in which the parts old and new still share similar layouts, and as in this case, the heater outlet thread hasn't changed since 1965 at least. (That being my guess at the date of Bitsa's current 2.25D, from which this valve was pinched)
The only snag with fitting this tap valve onto a tdi is that the rocker cover has to come off while fitting is in progress. Inside the rocker cover everything looks all neat and tidy, and very clean. More good news...
