It was popular in a lot of other areas too.  I'd forgotten completely about 
that being called a #6,  and still wonder what happened to the other numbers...

Yep.

I never did find out what its intended use was.  As things turned out I'd have 
been better off with a 6v lantern battery or something.  It didn't last long 
and I wouldn't be surprised to find that it had been on the shelf a while.

Another one that I'd forgotten about was the AF cell,  which I have four of in 
a meter here.  Bigger than AA in diameter,  at least.

Yep,  even though it was a chore to get 'em out of there.
