My understanding is that in a circuit like this, the condenser
is there to prevent arcing at the contacts.  The condenser takes
over the load from the air gap.  I was looking at this in
bright daylight, so if there was a small spark I would not have
seen it.

Barney mentioned this as well.  I'll need to measure it
again with an electronic meter.  It very well could have 
been just very low resistance.

Definitely chrome bumper.  I don't think there were
any rubber bumper MGAs.  :-)
