Just posted a new set of photos:

1477 Very Pistol... Flare Gun. Very is the inventor's name.1477 A bunch of vacuum tube shields. In the age of pictureless TV (called radio) there were primitive thingies that did what those trivial parts of ICs called transistors now do. Each of the vacuum tubes was supposed to do its own thing, and to isolate each of them from the others, it was not uncommon to slip Faraday shield cans over them. The pile of parts in the picture are for late model vacuum tubes ('50s).

What is it? Set 261

The aluminum ones had black anodized inserts for use as heat sinks. Glass envelope got too hot, otherwise. Was found on lots of military gear from the 1950's era.
