I have a Treadle, A Featherweight, A Serger, A Kenmore that received when graduated in 1981, A Viking Ruby, A Viking 400, A Vintage Singer (that need to figure date on though got it in '87), another Newer Kenmore, and then inherited a Kenmore that is similar to the I received in 81, and also inherited a Newer Brother. Oh and last but not least an APQS Longarm. I have used all of them except the brother and the Vintage Singer I haven't used lately. I guess that puts it at 12 but am NOT a collector...LOL....
