I have not been following this so my apology if I repeat someone.  But most
bipolar transistors will oscillate at a low frequency.  A simple AF
oscillator circuit will always find the E, B and C. The transistor will only
oscillate if it is correctly connected and will not destruct if not.   The
basic IC=beta IB can determine the beta with a couple of meters and variable
voltage in a very simple circuit.

There must be abundant information on transistor testing on the web.
