I just got a 66-16 at an auction and it was born in 1947. Mine has the exact cabinet and bench but not as many attachments. I paid $27.50 at the auction and I'm a happy camper.
That looks just like mine! I got it on half price day at an estate sale and paid $22 something. but no bench and no attachments. Still, I am so happy with it. I hope you enjoy yours too!!
