Any way to move industrial controls and get close to what they are worth?

You have to have them tested, calibrated and certified at an official cal-lab .
The other issue is - what exactly do you have ?! I have mostly dealt with industrial controls and instrumentation, and re-sellability is all based on what you have, the name brand, the condition, and the calibration certs !

( Example ) If you have a certified Rosemont differential pressure transmitter with Hart, I would have no issues paying $600 per unit .... on the other hand if you had an uncertifyed 'no name', I would not pay more than scrap.

It looks like the main control systems are for 'Smoke control system' but can also be used for other system controls. The Network 8000 boxes are remote satellite stations that I think allow you to hook up multiple controls which then get patched back to the main system. Here is a list of the equipment:

GCM-86110 INVENSYS / BARBER COLMAN (Siebe) qty 3
GCM-ECH-001 INVENSYS / BARBER COLMAN (Siebe) qty 3
MN-FLO3T INVENSYS / BARBER COLMAN (Siebe) Approx qty 20
Barber-Colman Network 8000 Global Control Satellite (Siebe) Approx qty 16

Ebay does have some sales of these items, but everyone lists them as bench tested and warrantied - since I don't know how I would even test them that is why I'm trying to sell as a lot.

Thanks everyone for the ideas, I will let you know what I find out.
