My understanding from different postings here in the past is that
- 507 C was used for some time after WW II as overall grey,
- this changed to Light Admiralty Grey, which was a duck egg blue (actually a greenish tone), in the 1960s,
- while from 1966 (or 1969?) Light Weatherworrks Grey, which has a slight blueish hue, came into use.

Is this still valid or did researches in the last years reveal different information?
