Depends on how the end plate is mounted. I assure you that is a Burman first type. Consult the Jaguar Service Manuals.
Here is S Type Manual which shows both. The short pipe is the first giveaway. The Second Type has a far longer pipe from top to front of box.

- LHD has end plate mounted so the oil outlet is facing upwards
- RHD has end plate mounted so the oil outlet is facing downwards
I‘m sure the experts can explain why…

I am no expert but Jeff is probably right and the orientation is just so the outlet does not foul against the engine when the steering box is swapped from RHD to LHD.
A picture of a RHD box next to a LHD box would show if we are thinking right. They should be identical apart from the outlet pipe. It would have saved Jaguar a lot of money if it was just a simple case of turning the end plate 180 degrees.

Here is a summary of what I found out:
- I could replace my LHD steering box by a LHD manual box. The mounting positions are compatible.
- The input spline drive shaft of the manual box is at a different position so that I cannot reuse the lower steering column. I would have to replace the lower steering column by the longer version used with manual steering.
- It is unclear whether I can reuse the Pitman arm and leave the steering linkages unchanged. I assume yes.
My current plan is to keep my PAS box (and lower steering column, Pitman arm and steering linkages) without the pump and reservoir. I am trying out using a high viscosity steering box lubricant (no leaks) and blocking off the fluid input and output. Plan B is to connect the input and output ports together.
I have managed to reduce the free play in the steering box by using shims above the thrust pad (since diagrams above) since thrust pads are no longer available.

Really interested in your reuse of the power steering gear as I’m considering doing something similar - converting the column to an electric column ( possibly from a Prius). What electric power steering did you use ( or if there is a thread already on this please point me to it), many thanks Michael
ps looking forward to your results on blocking the input output ports or looping them together

The previous owner had an EasyDrive electrical steering added. He left the original PAS system (box, pump and reservoir) installed and active (the pump being driven) for some unknown reason. Theoretically blocking the ports should work provided there is enough air in the system which can be compressed. Unfortunately I found resistance near the end of both locks. I don’t want to risk having too little oil in the box so I’m now going to try looping the ports together. I will report on that soon.

What would the advantage be of using a PAS box in this way rather than replacing it with a manual steering box? There are probably quite a few of those of those about, I just sold one complete with all the linkages to a guy in Germany (i'm in UK) and I think with postage via ebay it cost him around £150.
