I adore those skirted knobs. What could be better for an old-school mixer? By the way, those knobs are also known as "Collins knobs" since they were used on Collins radio equipment. When originals turn up on evilBay, they're usually snatched up by Collins restorers. I know that some guys with molding equipment were homebrewing small quantities of replicas; it's good to see that Davies Molding is making a version now.
