WTS Hmmwv Red-Dot evaporator - Asking fair value 1st

[GPW43]

I have a HMMWV 24V A/C KIT UNIVERSAL REDDOT EVAPORATOR R-2400-0 that is surplus to my need (got it years ago to put it in my HMMWV);
What is the fair going price for it;
Item is located in Bay Area (San Francisco, CA) and can be brought to the MVCC (CA collectors) show in April in Plymouth, CA.
Let me know as AC units were all over the place depending on when you got into it and then who was selling what back in those days. The picture is of the internet, the one I bought was never installed. No harness , only the evaporator unit.
Thx,
GP
