Thanks Jason! That certainly solves the mystery, it looks like that's exactly what was done. The evaporator still looks in remarkably good condition so I think I'll just re-use it. I believe the next step will be to contact Old Air and see what compressor and ancillaries they recommend to run with that setup.

I'd also like to either freshen up or replace the blower/evaporator box as it's rusty on the back and the diverter flap rubber seal has perished. Has anyone had experience with doing this, or working with vendors that do this? I see Original Air does offer a rebuild service.
