I have a pretty little vogue machine that had a bent tension assembly. DH fixed it but now we need the large nut and the numbered dial. I believe the vogue is a White clone? Should I look for a parts machine and go for a complete assembly or try ebay for the two missing parts and what assembly am I looking for? Do they go by the type of bobbin? or? Thanks so much for any suggestions. The picture is how she looked when I bought her.
