Based on the fact that you have no AC vents in your dash, you have the heater only control panel, and heater only heater core box in the engine compartment, I would say you have a heater only cab. Its possible that there used to be an old aftermarket under the dash AC unit judging by the leftover condenser hanging from your core support, and what appears to be an AC hose running through the firewall near the inside heater box.
