Brother KH820 knitting machine appeared on the market in 1974. It is a standard-gauge (4.5 mm) knitting machine with 200 needles.

It is the one of the first punch-card machines with this more modern design (maybe the second one, after Brother KH810). The same basic design was used on all consequent punchcard-capable knitting machines. Its predecessors (KH800 and KH801) had simpler punch card capabilities. Another older model (KH811, released in 1973) still had a pushbutton option on top of the punch card reader.

It also comes under the Jones brand (Jones KH820).

The carriage’s HCL knob has only two options: KC (to engage the timing belt) and NL (for stockinet knitting). The carriage has buttons for automatic knitting of tuck, fair-isle and part (slip)-stitches. The carriage is also capable of creating weaving and lace knits.

If the carriage gets jammed, it can be easily remove from the bed by raising the carriage release levers (they are on the side of the carriage).

The end caps for this machine are attached to the main body with metal screws, which I like a lot. Later models have plastic rivets instead. My guess they switched to plastic rivets because no metal reinforcing plates (square nuts) are required. These metal plates are also lost easily.
