Older window- or sliding door-style air conditioner. Not sure of manufacture or year. Worked great when I used it a couple years ago. Selling because I've since switched to floor-standing units. 37cm wide, 52cm tall, and 64cm deep. Asking $60. Hopefully it can help keep you cool this summer rather than sitting in my basement. Pickup in Esquimalt from a road-level garage (no stairs!)
