Brother KR710 ribber works with Brother KH710 knitting machine. From what I researched so far, it looks and operates similarly to the Brother KR830 ribbing attachment. It is also often branded as a Genie KR-710 ribber.

Enjoy the scarce pictures below while I look for additional information in this ribber.

Recently, I read a post stating that their Brother KR710 ribber worked with the Brother KH910 knitting machine. This is very interesting and means Brother KR710 ribber can work with punchcard and other electronic Brother knitting machine models.
