Yes Roobarb,

so if I well understand, the presence of this device shows that the plane had a manual (hand pumped) undercarriage retraction system, while when it was replaced by a hydraulic system driven by a pump, this tank and the new pump were moved to the engine firewall.

Isn’t it?

Thank you Mauld,

but I suspect this device was not a voltage regulator.

According to some sources “….on early Spitfire it was mounted low on the back of frame 11, directly behind the pilot’s seat [thus not visible]. Starting in the N30xx series this was repositioned higher on frame 11, appearing low in the rear transparency, and from N32xx it was mounted more higher, directly behind the pilot’s headrest”.

In addition, on some Spitfires both devices are installed:

This link gives some videos of Robert Stanford Tuck:-

thanks for the link but unfortunately no news about Hurricane V6555.

I suspect all the color profiles about this plane were made without photographic evidences, above all Churchill caricature on the fuselage. Hard to think there are so few information about this very famous fighter pilot like R.R.S. Tuck.
