Silver Reed LK330 knitting machine is a plastic-bed knitting machine with 140 needles, 6.5 mm apart. This is a mid-gauge knitting machine with only manual stitch manipulation capabilities. Silver LK-330 was very likely manufactured for the Japanese markets only. It is very similar to a very famous a Silver Reed LK150 model, on which there are a ton of resources online. Thus, refer to those while enjoying the pictures of this rare (to the Western markets) machine below.

PS. Do not confuse this machine with Silver SK330, which is a metal flat-bed machine with punchcard-reading (patterning) capabilities and 200 needles, 4.5 mm apart.
