Yesterday a customer sent me images of some of my late fathers 85mm figures he recently saw on sale at Blenheim Palace. I don't know any more about this but they appear to be factory painted.
www.toye.com still own all the masters, moulds and manufacturing rights for these figures but they stopped producing them about ten or so years ago, so these must be very old stock! Toye were last selling the single figures for around £160 so these are at a very good price.
