Thanks for the offer.  I'll try NJ first and contact you if I can't
find what I need.

"When in doubt, heat it up and hit it with a hammer."
Blacksmith's credo.

If it walks like a duck, and quacks like a duck, it is probably not a
cat.

Never a horse that cain't be rode,
And never a rider who cain't be throwed....
