[Test-Equipment] part for HP Directional coupler

[Ed White]

Hi Gang:
I am looking for a blown ,burnt out destroyed HP-11692d or any other 
Directional coupler that has a coax connector that is still useful. The 
coupler I have has one port (incident) that has a broken "N" center 
connector and is useless. the connector is in several sections what I 
need is the hole thing from flange  (Brass) to the "N" connector ( 
stainless steel) they are probably used on other directional couplers.
Any help will be great
