Singer mod. 151 knitting machine is a bulky (9 mm gauge) knitting machine with only basic patterning capabilities: all stitch and needle manipulations must be done by hand to create patterned knitted fabric.

Unlike its earlier counterpart, Singer mod. 150, Singer mod. 151 has built-in (into the sinker plate) weaving brushes.

Singer mod. 151 knitting machine is a clone of Silver Reed SK-151, on which I already wrote a detailed article, to which you can refer for further details.

Matching ribbers for this machine are Singer SR150 and potentially Sliver Reed SR151.
