Hello all,
So there are UK coilers,

I looked in yellow pages at sign manufacturers.  Found those that
specified
neon signs and made a few phone calls.  In the end a very helpfull lady
supplied me with a 10KV 50ma from a company in Bristol.  Infact it cost
me
nothing as my son was interested in the subject for a school project and
she took sympathy.  By the way a new one would cost about 80.00.
