The cockpit photo on page two this thread is of a T11 (did not have that recorded earlier) so I'll repost it here and add a ZOOM of the altimeter. Found my old interpretation of the three needled altimeter issue and can post a PDF about the loss of CMDR AIR at Nowra however it is only my guess work (from remembered limited info given to me at Nowra when I first arrived back in 1969). And I note different Vampire altimeters had different sized needles particularly width (never mind the quality feel the width).
2 page PDF attached now.
“The first needle (much shorter) showed the increments of 10,000 feet, while the second showed 1,000 feet and the third (longest needle) showed 100 foot numbered increments on the dial.”
