Brother KH220 knitting machine is a bulky (9 mm gauge) machine with only manual capabilities. It features 110 needles.

I did not knit on this machine but it looks very similar, if not identical, to Brother KH210 that I had a chance to work on: the color combination, the carriage shape, the needle markings, etc.

The machine is unique because it does not have gate pegs (similar to KH210) but has sinker needles and sinker hooks. The carriage has a built-in intarsia yarn holder.

This machine was very likely marketed to the Japanese market judging by the Japanese writing on the carriage.
