Simplicity sewing machine parts

Compatible serger knives, needle plates and presser feet for Simplicity sergers and sewing machines, each naming the Simplicity models it fits — the SL803, SL804 and SL843 sergers and the SL300 and SL4300 series sewing machines. The range is small; Simplicity machines were built by other manufacturers and several of these parts name a Baby Lock or Brother sibling as well.
