I have a 600. I'm not sure if it is an A model or not. I suspect, but do not know that it might be a model A or a plain 600, as it has a riveted "touch and sew" label on it. I've not used it. I found it at an estate sale for $45.00 and bought it.
I've cleaned it up and that's about it. It's pretty much like the 400 and 500. It has the built in cams. It's all metal. The only difference I've noticed is the bobbin style and the way the bobbin winds. Mine has a button on the bed, the later 600s have the button in the bobbin area like the later touch and sews.
What else do you want to know?
