Studio mod. 600 knitting machine features 200-needles, 4.5 mm apart, which makes this machine a standard-gauge one. It is a wonderful machine with built-in intarsia capabilities. It is also able to pattern using a punchcard reader. It is very similar to the Studio mod. 700, Singer mod. 700 and Singer MemoMatic 700 (on which I already wrote detailed blog posts) – they even share the same manual; however, Studio mod. 600 it does not have a built-in knit-leader and its row counter is detachable.
