With out being flippant, .01 second to 100 hours maximum, before total 
destruction!  

No input data!!

A small 6" tall coil with a .002ufd cap powered by a 10KVA pole pig using 
a two point tungsten static gap carefully ballasted back to the 20 watt 
level producing 6" sparks might run 1 year- non-stop!

A 4 foot diameter coil, 20' tall with a rotary using zinc points and a 
1ufd tank cap might last a fraction of a second.

In general pole transformers can survive about 10,000% longer in a well 
proportioned system than a neon tranaformer.  This assumes a lot of good, 
positive things about the builder/user!!!!  (always a sucker bet)

My advice:
Blow up at least 10 neons and oil burner xfrmers before getting a pig!
You'll leran more with a higher probability of be around around to take 
delivery on the the pig.
