I believe I may have the missing knob. I know I have seen it but didn't realize what it was from. The unit is located in NE Wisconsin in Townsend (about 85 miles NW of Green Bay.
I have a Murray Corporation of America (Easy Laundry Div) washer Model SDK, SN85533, that is in very good shape. It was in a property I bought in 1987 and has been stored in the garage since that time. I can provide a picture if necessary. My question is does this have any value?
