The gold I see is the old components that are not being made any longer. A little research lead me to believe they are the first junction transistors made by TI. The story line goes like this. TI bought a license and the machine to make them from IBM. TI produced them for IBM. The numbers should have a date and component ID in them. In that day they even gave each device a serial number (some not all). So I make a giant leap and say it is an IBM device made by TI and excess IBM couldn't use was sold to GE. So what's in that TO5 can?
I removed the top on a couple I had in the parts bin to see how they compare to the IBM.
* The ones I disassembled are Russia 39B PNP.
** The boards arrived. I found four transistors with different marking. They all tested good. They were all PNP types with different ß and forward voltage. The Transistor Museum had an article showing some like mine and noted they have different colored epoxy filler. They questioned if the color was a code, maybe type ID? I tested some green and black ones. They were all PNP but did have different ß and forward voltage. If there is a code I failed to see it.
