Verdict: It works really really well!
@cm2 😁 This one is called the Juice-O-Mat. There are some sifferent but mostly similar variations of this, some called Juice-O-Matic. If you are in the USA they are pretty common. I've seen quite a few of them at vintage/antique/flea markets. You may have to look around a bit to find one in good shape though.
