"I have heard one person say that a bombarder is current limited, and
one
say not.
Anyone else out there have an opnion?

        I have a copy of "NEON SIGNS" by Miller and Fink (bought
from Lindsay Publications, which describes bombarder transformers
as being at least 5 kVa and require EXTERNAL current limiting.  
Figure 73, page 171 shows three circuits for limiting and
regulating the current.  First uses a series resistor (rheostat), 
second uses a tapped autotransformer (this is 1935, variacs were
not around yet as far as I know) which controls the voltage, and
third shows a series inductor with sliding iron core.
