Late 1960's Valve box
Changing to the bolder, but
simpler black and blue design with the "Big-M" logo - this is
quite effective. The now common customer panel is present.
Early 1960's Valve box
One of the far better wrap-around designs using three simple colours (red,
blue and black). During this period AEI used the same design with Ediswan
valve boxes. Side four is stamped with the valve details. Impossibly
pointed valve top would get easily broken off.
1950's Valve box
Ah that's better the good old
Mazda logo. What lovely indented corners reminiscent of older times.
I also have samples of sides 3 being blank
(like side 2 without the info sticker), and other samples where side 3 has an info
sticker covering what looks like a guarantee.
