Lowell Gauge

[David Love]

So I pulled my Lowell Gauge out of my case, after not looking at it for
a month or so, to use it to check the bearing on this piano I was
inspecting and much to my surprise, the little tiny bubble had grown to
a rather large bubble.  No evidence of leakage.  I'm wondering what I
can do about it.  It looks like the liquid inside is anti-freeze (sort
of greenish).  Can one replace the fluid to the proper level leaving a
small little bubble instead of a large useless bubble?  Or can I buy
another one somewhere?
