Here’s an oldie but a goodie! I have found lots of Juice King juicers on the internet, but none of them were like this one. Basic differences of this one are the cone-shaped crusher, pointed feet and pointed handle. The number on the bottom is JK-4A; however, the number on the handle is JK-3A. I’m thinking part numbers instead of model number?? Another difference is the metal plate between the feet. Other juicers I’ve found either have no plate there or the plate is a solid, entire bottom piece. Age? I simply don’t know, but will guess at late 1920s to early 1030s. If you know, please let me know! I will consider offers on this piece. Thanks for looking!
