Jane you can find most of those items you need at Sew-Classic or Aprils1930s online. I got a 301a that needed cord, new feet on the bottom, new tensioner, new bobbin winder donut, new felts on the spool pins, etc. etc. Got it all at those 2 places for good prices. Don't you just love the 301's?? Even though your serial number said 1951, all the serial numbers for the 301s were allotted in 1951, and they didn't keep records of when the actual machines were made. So, anytime between 1951 and 1954, is best guess I have seen researching my 301a.
