How does the gain of a transistor go down ... ?

You need to look at those transistors on a curve tracer. I bet one of them
is leaky - acts similar to having a resistor paralleled from E-C.

I don't think I still have them. That said, although my workshop component
tester is only a cheap little Chinese thing, it's usually pretty good at
picking up stuff like leakage, and it didn't say that it found anything
other than a working transistor with no problems other than that the gain
was low (significantly so compared to the other one in the pair, that is).
I agree though, that this doesn't mean that there wasn't some kind of
leakage either too small or too subtle for the tester to register.
