Lecle Pattern Book for MK-70 & HK-160 Knitting Machines
Lecle 18 stitch punch card pattern book. A free link to the full text (and photos) from this book is available a little further down on my pinterest page.
Demonstration of MK-70. It's definitely worth watching. Unfortunately, it doesn't show the MK-70 knitting, and it leaves out other information that could be useful to potential buyers and new users of this machine.
