Thanks, all, for the responses!  The way it measures out makes it look like
it may be an MJ10006 or similar.  I think it's probably ok.

I poked around a bit more this morning and it's looking like part of the
flyback is shorted out -- we have a 2382 at the museum and I popped it open
just now and I verified that it measures differently (i.e "not shorted" :))
at the same points.  So that's likely my problem.  Drat.
