Silver Reed machines were produced first but then the company renamed itself into a Silver Seiko and the machines started being released under the Silver name. Then after a while, the machines were named again Silver Reed but also (as the company’s market was expanding) as Singer, Studio, Empisal, Riccar, KnitMaster, and Elna. Silver Reed also has a line manufactured under “My Studio” nickname.
So, all those model numbers are interchangeable even though the names might differ. If you don’t see a model number of interest here, check the Silver, Singer and Studio pages.
Silver/Silver Reed/Studio/Singer knitting machines, especially, metal flat-beds, have somewhat different mechanisms than other knitting machines (although there are some overlaps). Thus, they sometimes need a different approach to handle carriage problems than machines might. Some of them are covered in my article.
