Yes, Hawker painted all their aircraft wheel wells in Aluminium, including the Typhoon and the Tempest. The inner faces of the landing gear doors were also this colour. As far as I remember, the only surviving (almost complete) Typhoon, in the RAF Museum, has the 'silver' wheel wells. I have seen some colour pics where this appears to be green, but close examination shows it's a colour cast from the lighting - unless it's been re-painted since I saw it last!
There are a couple of things not quite right with the RAF Museum Typhoon, through no fault of the restorers at RAF St.Athan.
The aircraft was returned from the USA with some parts missing, and some re-painting had also been done whilst in the US.
False ailerons had to be made, and the radiator is the front of a truck item, with plywood and card sides, and canvas trunking !
The spinner is made from two pieces from, I believe, a Varsity or Valleta, or perhaps a Bristol Freighter, and the prop is fitted as best as possible, at the wrong pitch angle, which was unavoidable. There are other items, such as cowling panels, which had to be fabricated, and therefore lack the internal stiffeners, and consequently, there are no rivet lines where these would normally be.
In at least one photo of the cockpit, it can be seen that there are American additions, such as the yellow tape around the 'basic six' flight instruments, and an American-produced pilot's manual !
As a restoration for display purposes, and especially as it's the only almost complete survivor, it is superb. But as an accurate reference for modellers, extreme caution is advised !
