The Murad 3Q capstan was the most popular of the company repetition  lathes and remained in production from World War 2 until the 1970s. For its capacity it was a heavy machine, though notably compact in comparison with competitor machines, and featured the use of foot-operated electrical speed-control switches that significantly reduced the number of occasions when the operator had to stop the lathe, open the cast-iron cover over the motor to drive run and change the belt from pulley to pulley.
