There are two guage glasses.
Not on Western Locomotives. They have only one with two small cocks at
the levels of the top and bottom of the gauge glass to make sure the
boiler is somewhere in between.

I would have thought that if the boiler was missing, you might notice it
without the need for small cocks top and bottom!
