Dan and Ed,

I will try to decipher the full letters and post them in typed form to my 
site as well as digital...

As for Tesla-Thomson, I am referring to commercial Tesla Coils in terms of 
manufacturing "for sale", not the actual priorities of the invention itself. 
  Thomson had hundreds (698?) of patents too, and unfortunately I haven't 
seen a list like we often see of Tesla's patents.  I've seen them in 
searching over the years, but did not choose to save them.

I do recall though that the patent for this X-Ray system was for the 
air-blast spark gap, the complete Tesla Coil circuit being used as a 
functioning example of using such...this was how many hundreds of Tesla 
Coils were patented over the years...the little details in the particulars 
that made them "unique".

The history of Tesla coils is really complicated.  We're trying to sort it 
out, and any input is more than welcome.
