Aftermarket Aircon

[Headlights]

Anyone else had aircon retrofitted to their chimp? My condenser has had it, Austec had a look at it and told me it was'nt a TVR aircon system, I have no record of the work being done by a previous owner. When the system was working, it did actually produce cold air! worth fixing if I can.
any ideas ??

might get it re-conned by an a/c specialist?
