Tried this just now, got 0V both open and closed.

Also saw 0V with this test, but I also realized my original
"short" mistake - big dummy didn't disconnect the coil
before measuring the resistance! :-P With it disconnected,
it shows *open* on the primary winding. D'oh!
So I'm thinking I had the right diagnosis but for the
wrong reason. That's worth partial credit, isn't it?
I'll try a new coil. Thanks everyone for the help.

Oh, the subtle but pervasive MGB prejudice that permeates
this list! :-)
