I did not have experience with this machine and the pictures below were provided by someone else. It is a standard (4.5 mm) gauge machine with 200 needles and patterning capabilities through punchcards. It is also branded as Palie (similar to some other models).
It is a standard machine with built-in knit leader. It seems that all brother punch card machines ending with “1” are with built-in knit leader, like KH881 and KH891.
It comes with cream/orange color combo. It is very likely was made for a Japanese market only because of the abundance of Japanese writing on the carriage and case.
The machine should come with all standard assesories on addition to the assesories for the built-in knit leader. The scale gauges often get lost for these machines but you can look up their photocopies in here as well.
It is very similar to knitting machines with punchcard readers, like Brother KH881 and KH891, as well as to other punch-card Brother machines but without built-in knit leader (KH800, KH810, KH820, KH830, KH836, KH838, KH840, KH860, KH864, KH868, KH880, KH 890, KH892 and KH894).
