This is a printed hard copy, scanned from an original, of the manual for the Singer 201K Lightweight sewing machine. This is the later version of the 201, mecchanically identical to the original but, instead of heavy cast-iron it is made from 'lightweight' aluminium. It's still pretty heavy by today's standards but is only about half the wight of the earlier one. We also can supply this manual as a pdf download which you will find on a separate listing.
It has 34 pages and postage on hard copies is free.
You can verify whether you have the correct manual for your machine by comparing it with the picture.
