I have a battery operated beacon monitor receiver that took an 'F' cell 
for the filament

What make/model receiver uses those?

I don't' recall seeing F cells on the shelf, but I used to pull them 
from lantern batteries when I was very young.

I haven't seen bell batteries on the shelves since the 70's, and from 
what I understand, the very few still on the market have large plastic 
cases with a singe D cell inside, and are now called "ignition 
batteries", no longer used to ring a local bell, but start model engines.

AAAA batteries were hard to come by, and expensive 50 years ago, so I'd 
pull them from relatively expensive 9 volt batteries.  Cheapo 9V 
batteries had carbon piles in them.

The worst was 1/4 AA, I think that's the size, in a  mercury cell.  I 
have a pocket radio that uses two, and 40-50 years ago, they were about 
$7 each.  Dad had a fit.  That's more than $38 per battery nowadays!  He 
promptly glued a AAA battery holder to the radio, and we got some free 
battery club cards from Radio Shack.  There was also an F size, but in 
12V with large snap-on connectors on the ends, I recall those in smoke 
alarms in the 70's, another freakishly expensive battery.
