I was looking around in some of my junk boxes, I also have an old
RAY-O-VAC yellow and dark blue and red D cell battery.The RAY-O-VAC
trade mark/logo is red with the name Ray-O-VAC in white letters.The red
and white trade mark/logo is between two halves of a vey dark blue dot
on both sides of the battery.Some old batteries are collectible
nowadays, same as many other kinds of old things.Everything Old Is New
Again.
