Pressurized Spitfire question

I believe that the HF MkVI were operated with pressurised cockpits to counter the high-flying JU86 reconnaissance aircraft. I recall that it was fitted with an uprated supercharger (1415 hp) driving a four bladed prop, the cockpit canopy was actually bolted into place and that the wing span was extended.

The first 21 MkXIX were unpressurised, the remainder were.

The PRXIII was for low-level stuff, and accordingly it was still armed with machine-guns and fitted with an armoured windscreen.

Thank you for the swift replies; I am translating a document from the Swedish, and it seems that I must correct the original author, as it would apparently not even be true to qualify this statement by adding “during WW2”.

Hello Papa

My references say Mk VI, Mk VII, PR X and PR XIX were pressurized.

Cheers,

Papa,

There were also the Mk VI, some Mk VII’s (not sure), the PR XI and the Mk (PR?) XIII?

Some I’m sure of, the ones with the questionmark not totally.

Please enlighten me
