Frigidaire AC window unit

I've got a gently used Frigidaire AC window unit. It's this model: Frigidaire 5,000 BTU 115V Window-Mounted Mini-Compact Air Conditioner w/ Mechanical Controls, FFRA0511Q1

It works well -- I've used it around 10-20 days over the past couple of years -- but my nonstandard window means it's been impossible to create a good seal around the unit, so I've had to get a different version. All to say, would love to find a new home for this and recoup a bit of the cost of buying two AC units in as many years!

Pick-up from downtown Palo Alto.
