Hey! That's a positive comment/question.

Below is a close-up of an object that has been in my junkbox for over 58 years. I know exactly what it is, but do you? Let's hear what you think it is and give as much detail as you can.

Looks rather like an antique transistor.

Well James, you've won the NERD award. This device is a little more than an antique transistor. It was the second commercially available transistor. A Germanium devicw of the PNP variety. The 2N107. I should have put a dime next to it to reference the size. The metal case is particularly funny. The vacuum void created then 'hermetically' sealed, was useless. There really wasn't a need to put the Germanium junction into a vacuum, like the old vacuum tubes. Germanium was used on this first generation transistor until they found a way to 'grow' silicon crystals to mass produce transistors. Each one of these had a footprint slightly smsller than a dime. A 'Smartphone' has over a million transistors in it. Imagine having one packed with these beauties. Even your DCC decoder would be larger than the locomotive.

Lou,

Bud Collier would have said "Beat the Clock!". Excellent answer! An 'A' grade.

Larry, not exactly, but your heart was in it!

Well I was going to ask the size and if it could be converted to a top hat. I guess that is out of the question except for G scale.

It's an electronic doo-dad! I realize that term may be too advanced for some people here but that's life.

I should steal that award away from James.
The question was "Let's hear what you think it is and give as much detail as you can"
James just said a general answer.
I gave you the whole enchilada.
So I proclaim the Nerd Award!

You better grab it while he's got the old welding helmet on, That newfangled aotodarkening one, won't let you sneak up on him.
