D.W.S. Hydraulic Jack

[47p2]

Does anyone know what this jacking system consists of, looks like or even has a picture or information sheet?
Is it a fitted system similar to the Jackall hydraulic type fitted to numerous cars of the same period as the P2

Maybe this is of any use: http://www.mattboyd.org/cars/p3/tech/jacks/" target="_blank" target="_blank

Here the jack is first mentioned to be used:

Wraith 1938 - 1939.
The 25/30 Wraith continued with a 4 1/4 litre engine but the main difference was the fitting of independent front suspension controlled by coil springs. Road wheels were reduced from 19" on the 25/30 to 17". Built-in hydraulic jacks were operated by a hand-pump under the driver's seat. The Wraith was slightly heavier than it's predecessor but cruising between 60 and 70 mph was possible.
491 were made before events of 1939 stopped production.

I had read that article Job thank you, but I'm not sure that the Rover P2 set-up was the same.
Hopefully someone from the forum will be able to clarify this
