Early Post WW2 RAF Instrument Flying Goggles Mk2 (Unissued & unopened)

An unissued pair of early post WW2 RAF Mk2 instrument flying goggles that are still sealed within their plastic protective covering.
The Mk2 goggles bear the stores reference 22c/1136 along with the makers name of Polaroid.
Two pairs were acquired both sealed, one was opened for inspection purposes and was found to be in very good order apart from some light rusting on the strap buckle, the moulded black rubber frame with chamois backing is also in good order with only minimal age related stiffening.
The deep blue tinted celluloid window filter is intact and free from any damage/scratches .
Please note that the opened pair of goggles seen in images are not the ones currently for sale it is the untouched/sealed pair so I would presume that they are in a similar condition.
