Brother KH587 knitting machine is an 8-push button knitting machine with a pattern control center. It is a metal flat-bed knitting machine with 200 needles positioned 4.5 mm apart, which makes this knitting machine standard.
I did not have a chance yet to see this machine in real life and/or work on it. Below are pictures generously provided by other knitting machine enthusiasts and posted here with their permission.
Brother KH587 is almost identical (with the exception of color) to Brother KH588.
