You're probably right about them being only slightly valuable but it's
still interesting to look at. Most people today have nver seen the inside
of a battery and have no idea what they look like. This battery was built
by Willard. I took a picture today and posted it at

Hi
Seems to be a standard Lead Acid cell. I have some Silver Zinc
cells that are dry stored that look similar. These use
an alkali unlike the lead acid cells.
I forgot to mention yesterday that I also picked up a battery for a
radiosonde. It's still sealed in it's orginal can so I don't know what it
looks like but the guy that I got it from says that he thinks it's a
Lithium battery. The date on the can is Sept 12, 1982 and it was made by
VIZ. I don't know exactly who VIZ is/was but they seemed to have taken over
production of cheap test equipment from RCA. I've seen their name along
with RCA's on a lot of educational grade electrical equipment. I've posted
a picture of this one too. it's at
<http://www.classiccmp.org/hp/battery/radiosonde.jpg>. FWIW I used to have
a radiosonde but the battery for it was MUCH larger than this.
Most likely for a transistor unit, being from the 80's. I have
two old tube radiosondes that I've collected.
Finally, I took pictures of the two odd tubes that I got. They're at
<http://www.classiccmp.org/hp/battery/tube1.jpg> and
<http://www.classiccmp.org/hp/battery/tube2.jpg>. The filament is in the
large bulb at the side of the main tube. Only the first tube is marked.
"73" has been painted near the center of it. The can see it in the photo
but it's upside down. It was not printed but instead it looks like it was
painted on with a small brash. Only the first tube has the silver getter
material in it. Anyone have any idea what these might be for?
I'll bet it is some kind of arc lamp.
