That's a Seeger-made Coldspot. Since it's not mentioned in the ad, I assume it's non-working. It looks similar to the '57 bottom-mount Coldspot I came across several months ago, which worked but didn't cool adequately. It looks like this fridge is a couple of years newer, but I don't know the exact year when Whirlpool and its frost-free models were introduced into the Coldspot line-up. Maybe 1960 or for sure 61, since my sister had a humongous 1961 bottom mount WP-sourced Coldspot.
I think there's a good chance that the washer and dryer won't sell. If that happens, conditions will be perfect for low-baller's delight.
