FWIW, when I first got my '85 Westy, back in '02, it was obvious that
the thermostat was stuck open.  When I removed it for replacement it
looked normal and opened and shut with the "pot of water on the stove"
test.  Anyway, the replacement thermostat worked properly and still
does.  I tossed the old one in spite of the test.  It apparently would
stick in use.  I don't know what brand it was.
