Gary,

Well done on the documentation side of things.  This subject is also touched 
upon nicely in the Century Magazine article from April 1895: (The capital 
"A" in "MAgazine" is a valid typo for the link)

The incadescent bulb lit:

Of particular interest in that article is the steam powered Oscillator:

As a point of curiosity, Tesla's work in this field inspired Edison to jump 
on the bandwagon.  Edison's bulbs were simply Crookes or X-Ray tubes with 
phosphors on the insides of the glass.
