I have a 201K with a belt driven motor, the belt adds to noise. Since the hand crank version is almost noisless, and the motor itself is rather quiet, I assume the belt adds quite a bit of noise. The 201K2 is few and far between here, well, alt least compared to the belt driven version. My 201 is not very fast, but fast enough for me (as fast and some new machines), I have two much speedier zigaggers. It's closer to my 99 and 66 when it comes to noise, though it runs smoother. My 99 runs faster than my 201 for some reason, but I suspect the motor on my 201 could use a cleaning and greasing. From the information I read on the web, most vintage Australian Singers were made in Scotland (Kilbowie), they have the same 220V motor and light setup.
