There is a Parker metering valve on evil bay right now, someone might go ahead and grab it.
it is the stainless steel NS model, flow precision is about the same as a swagelok M series metering valve.

Oldpunk, that is a lovely stainless steel setup you have, what is the maker of the reg? Air products?
