the 'orange' paint on some numbers/lettering is the luminous paint that's 'gone off' with age. originally this would have been a creamy white colour and early on quite thick/blobby in appearance
of course the 'nightlight' view should make these 'orange' letters/numbers only 'glow'
(at least we no longer have the green numbering of late/post war instruments seen in early wip pics

)
spot on as usual with other points
