The earlier versions of this type of meter, rated up to 35,000 feet, were used in WW2 iconic aircraft such as the Spitfire, Hurricane, and AVRO Lancaster. The meter rated to 45,000 feet was required for aircraft with pressurised cockpits / cabins. This tended to be aircraft operating at high altitude for photo-reconnaissance such as 

• The Supermarine Spitfire PR XIX, introduced in 1944, which could fly at heights up to 42,000 feet.
• The De Havilland Mosquito PR Mk 32, a higher altitude version of the Mosquito PR Mk XVI with a pressurised cabin, and longer / lighter wings. 

However, there were some WW2 High Altitude Fliers with pressurised cockpits including the Supermarine Spitfire HF MK VI. The canopy was locked in place and it had longer wings than the lower altitude Spitfire fighters.

A very nice aviation collectible.
