vintage red BURRITE plastic salt/pepper shakers

I'll guess 1960's for these but they may be a little older or newer, I don't know for sure. From an estate-box, how could I resist this bright red pair with white screw caps -- they were kinda grungy dirty (well used?!) but are perfectly intact. Measuring about 4" tall and 3" across, they're made of injection molded plastic by BURROUGHS MFG. CORP. of LOS ANGELES CALIF., that is on their bottoms as well as U.S.A. and [#]508 with the BURRITE name in an oval. Each one has a large S or P on its side, the caps are white plastic.

They're gonna look *just fine* joining the rest of the red stuff hanging around my kitchen...? ;-) :-) :-) :-)
