I can tell you that from what I can see the 158 series machines are the ones that have this system and I know for a fact that the 158.17600 has them. I know that because I have that machine.
According to what I can glean, the 158.14 series, the 158.1600, 1700, 1800 and 1900 also has them. These would be the ones made by Jaguar/Maruzen.
I believe the 158.10400 machines have the extra pulley.
That PDF is very interesting. It appears that all 2 pulley machines are 158s, but maybe not all 158s have the double pulleys. Definitely gives me something to work with. Thanks!
