Thanks to all who answered - the solution was a fire equipment company
(Chief Fire Equipment and Service Company, Lodi, NJ). They take two
days and charge $ 17.75 plus tax.

Try a Fire Extinguisher shop, *that's where the SCUBA folks sent
me. * *They were great, *This shop only tests twice a week, so 4 day
turn-around. *Reasonable price, around $25 as I remember. * They
answered all my questions. *Also, I asked for and did get a tour of
their test facility and an explanation of how a cylinder is tested.
It was all very interesting and worth a quick tour.
