The picture of the manual below is the only evidence I found so far that the Jones KR582 ribbing attachment exists.
However, it is very likely a ribber to work with the pushbutton Brother and Jones and Genie 8-pushbutton knitting machines.
It is also very likely similar to either Brother KR580 or Brother/Jones KR586 ribbers.
… more info is coming as soon as I have it.
