Rick, try Smith-Watkins; they have done a lot of work with impedance and pulse-response characterization of trumpets and cornets. They are willing to share some of their hard-earned knowledge, but are (understandably) keeping some as trade secrets.
The glossy brochure they offer (for free), includes some technical papers, and they have been pretty good about answering questions.
