No telling Richard, but there are quite a few of them in my house...I love old singer sewing machines...my last find was a a gear drive Singer of British manufacture...1929 if I recall correctly...sews like balls of fire....a neighbor lady who I help care for, as she had a stroke last year and lives alone has a british middleweight which was her mothers...I got it out and cleaned and oiled it the other day..also works well...

it is not too hard to learn, particularly if you start with an older machine with no bells and whistles...
