This is the first (AND only) machine I researched and saw pictures of of that is designed to knit ONLY lace. Thus, the “L” in the model name: Silver SK250L.

Silver SK-250L has 200 needles, so it is very likely a standard-gauge knitting machine with punchcard-reading/patterning capabilities. Most accessories are standard but notice a very unusual looking sinker plate: with the brush-wheel in the middle. That’s all I know/notice so far. So stay tuned while enjoying the picture below.
