There are two major “branches” of Empisal knitting machines. Brother sold some of its machines under the Empisal brand in Australia and New Zealand (probably after purchasing rights for that distribution channel or that branch).


Silver Reed manufacturer of knitting machines bought the distribution rights for knitting machines in the UK and therefore Silver Reed machines coming from the UK are branded under Empisal as well (very often with the added “Knitmaster” surname to it).
Empisal by Brother and Empisal by Silver Reed have different looks, and features and therefore are easy to distinguish. Well, join me on this journey – figuring out which Empisal machines resemble Brother ones and which Silver Reed’s. So far, I discovered that Empisal models with the “Knitmaster” word followed by are identical to the machines manufactured by Silver/Silver Reed company (which also come under Studio/Singer brand names). Silver Reed sold under the “Empisal Knitmaster” mostly in the UK markets.
For now, the list below shows all machines branded under the Empisal name.

Mid-gauge
The machines below are 8 mm gauge. Some call them bulky, some call them mid-gauge. I knitted on one of those machines and I felt that yarns that are accepted by other bulky machines did not knit as well on the Empisal 8 mm machines. Thus, I am placing them in the mid-gauge category.
