[Collins] Transistor Question

[Merle]

Hello to the list.

I have a transistor I can not identify, wonder if anyone on the list has the information on this guy..??

It is out of a " tubester "  that some people used in their Collins radios back a while ago.

The numbers on it are: AT 5058 and on the other end of it is another number T 1402C or it might be TI  402C  anyway it is not in any of my reference books ! Any help would be appreciated.

73 and thanks
