Brent:

Perhaps a prior owner cleaned out the plaster etc , intending to insert 
a new vial, as you intend, but for some reason failed to do so. Death, 
incapacity etc sometimes intervene. I have wondered what MLW would do 
should she have to deal with the bits & bobs of my projects in progress. 
I rather doubt she would seek out missing parts.. .


FWIW
