Identify motorola transistor
Cyclotron:
I bought an electronics workbench on the FB marketplace and found some old components from when it was used at a GE factory.
I've been attempting to identify these transistors in the attached image, but so far, no luck.
Does anyone recognize them?
fzabkar:
Could it be this?

Probably not, as that is a Germanium transistor in a TO-39 metal can package.
It's possible it's a house coded generic part, labelled for GE.

Benta:
Certainly custom marking. No telling what they are.
joeqsmith:
We would commonly have them mark parts for us where I worked. I too suspect this is what you have. We would do this even with standard parts. It may be a common part.
Start by checking if they are NPN, Darlington...
Case is not the common EBC and I doubt they made too many TO92 case style 14(?). Download a copy of their old 1980's small signal transistor databook. Search for the case style. Should narrow it down pretty fast. If you can't Google find a databook, let me know as I am sure I have a PDF somewhere.
In the end, do you really care? Do you have a few reels or something and you have a need?
