These transistors were purchased from an aviation inventory surplus sale. We do not know the history of them. They are not tagged as to the condition status. The transistors themselves are marked, "KA4580, TI210". The label also reads, "NPN SKA4580, Bendix". It is in good cosmetic condition. We are not able to test it. It only comes with what is shown in the pictures.
