Great to see you back at it Gerry - I've been looking forward to seeing more!
Whilst I can't be definite regarding the bottles, all period photos I've seen appear to show them in the interior Grey Green colour, same as the master reservoir on the port side. These photos are, of course, B&W, but the tonal rendition is the same as the surroundings. Also, colour coding of pressure vessels and similar containers, didn't really start until quite some time after WW2, although (fixed) oxygen bottles, as part of the aircraft crew oxygen supply, were black, to denote 'clean' oxygen, as opposed to air, which may contain impurities, water etc.
Note the light grey air bottles - these appear to be to conform to modern safety and I.D. standards, with the appropriate 'modern' stencilling, but with a concession to authenticity by having the domed ends painted in the interior colour.
