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 <http://www.classiccmp.org/hp/battery/willard.jpg>. 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. 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? Joe
