R.A.F. Ground Equipment Blue-paint
The original request asked the RAF Ground Equipment blue for an ex RAF railway item.
I have now established that BS 381c (1931 addition) tint 69 Traffic Blue did indeed survive beyond the exercise to give 3 numerals . I have now established that it remained on BS 381c until declared obselescent in 1980 as BS 381c tint 169.
