I seem to have alot of attachments found with the old machines I buy. The Necchi BU, i just got had 3 diff. type bobbins in its cabnit. There were 20 bobbins made in Italy for it, plus necchi needles. From all my various finds I have probably at least 10 dif. bobbin type/sizes. Is there a place to find out what bobbins go with what? I only have the one bobbin that goes in the Pfaff 130 and it is pretty solid looking. I have bobbins that were made in germany and Japan. :S
