Here’s my 403A that Heather gave me installed in the cabinet I bought this weekend. I’m selling the machine on the left (a 1960’s 600e Touch and Sew), on Craigslist if anyone is interested.
Looks good, right? The lever sticking out underneath is a “knee lift.” Basically you drop the foot pedal in a slot and when you push against the lever with your knee, it operates the machine. Pretty sweet.
AND — you have to see this — here’s the original ad for Singer Cabinets. My cabinet is the Copenhagen model.
