There are currently at least two up for bid on ebay:



If that URL is too long try:



There are probably others being sold as part of various pieces of equipment
if you know what equipment to look for.

I think the last regular supplier that I ordered them from was Hosfelt
Electronics, but a search of their site turns up nothing.

I came across a "cluster bomb" at a garage sale over the weekend. It was
spherical, metallic, about 5 cm in diameter, and not perfectly smooth.
Rather, it had parts protruding out like a pinwheel. Said it was at least
20 years old. I guess these things were dropped from a larger cannister,
which then exploded -- sending these smaller "bombs" toward people.

I've never heard of such a thing. Anyone know if these claims are true?
What conflicts/wars these things were used in, and are they used in
today's combat?

Always check ebay. Nothing under ip39. But ip-39, aha!

If you don't get that one, try Kevin at www.houseofscience.com. He has a
big collection of obsolete physics devices in his store, also vacuum
tubes.
