I guess you'd call it a medium one. I went measure it today and it is 3 feet tall, a little over 2 feet front to back and just under 4 feet long. I had envisioned it a little bigger when I posted last night. It is metallic lined with some kind of acrylic or plastic coating? It's white inside but there's a spot of rust so it's a coating of some kind.
It is in real nice shape. I brought it home from a roadside giveaway thinking I'd see if it still worked. It runs but does not get cold at all nor does the compressor side get warm to the touch. Probably needs a recharge but I have no idea how nor want to spend the money as I have a working smaller one already.
Figured someone may want it for a bait setup. I kept some Dace in it for awhile last Spring/early Summer out behind my garage but figured someone could put it to better use. Just keep it in mind if someone asks, it's not going far for now.
