chergram, those bobbins are readily available. Try a sewing store or April1930sshoppe.com Billy may have some, too. April has lots of FW accessories.
My youngest daughter just called. There is "a black Singer with no flowers in a cute cabinet" for $75 at the Salvation Army. Shall we call her an enabler?
