Vintage .375H&H cartridge box..

[Pondoro]

Gentlemen, I have this old Kynoch box that puzzles me. The yellow-red boxes came somewhere in the 1930s, the mustard colored ones in the pic are fairly common...and somewhat older, but look at the one at the top, red writing on white background ..?

I bought it along with some other Kynoch boxes some 20 years ago....is anyone familiar with boxes of that color..?
