What does the -2 mean in the designation 201-2 and where would you find that? I have a 201 from April 1952, serial # AK899322 that I bought at a yard sale about 1.5 yrs ago for 40.00 and I love it. Since I have four machines (actually 5, if you count the red eye 66 I bought last fall but haven't sewn with yet), I try to alternate which machine I use for each project to keep them all moving so they don't get set up.
