They used to say in the 1940s and 50s that a 201k would cost 6 months wages for a very skilled tailor............most of them were sold on the "drip", one of the first hire purchase schemes ever............most good tailors reckoned that the 201 would repay it's outlay in two years, they called them the Rolls Royce of sewing machines, and many still do; they were the first machine where everything was rotary, i.e. nothing goes back and forth, everything turns including the drive which a really heavily over-engineered metal gearing system. All these machines are lovely to use, but when you get behind a 201 they're so incredibly smooth and quiet, absolutely no vibration whatsoever. Many think that Singer nearly went bust because they never had any repeat business - how would you ever need to buy another?
