Doing this gets me about .69 on two of the transistors, the other is .74Do a diode test on the two pins, and note whether you get a reading with the red lead to the base, or with the red lead to the emitter.
Do another diode test between the base pin (from @bertus ‘s diagram) and the case. You should get reading one way round but not the other.
The repeat between emitter and case. You should get no reading either way round.
if the base-emitter reading is above 0.5 then it is probably a silicon Transistor, below 0.2 germanium.
