	If I remember correctly, back in the `50's, I had a "portable", tube-
type Silvertone (Sears) brown-plastic AM radio which used two types of batter-
ies, one of which was an "A". There were two used in each radio, along with a-
another, which was large & flat-oval shaped. Anyway, the "A"'s were about the
size of 1.66 - to 2 times as long as 2 "D" cells stacked end-to-end. I believe
they were 1.5 volts each.
	The other, larger battery laid in the bottom & had a much greater volt-
age, like 12.5, or something.  The "A"'s stood up, one on each end of the radio.

	That's all I remember, besides 1) the radio only got about 100 hours
out of a set of batteries, & 2) they weren't cheap, by standards of the day.
