Singer AG20 intarsia carriage fits almost all standard-gauge knitting machines manufactured under the Silver/Silver Reed/Empisal Knitmaster/Singer/Studio/RICCAR names (except for the turn-knob ones) and several of first generation punchcard machines. It even fits some fine-gauge machines but with some modifications (the step-wheel/gear needs to be replaced).

It operates as a typical intarsia carriage and can knit intarsia colored patterns as well as plain stockinet. Refer to the manual for further details.
