Is anyone a knitting machine enthusiast?
 

I have a Passap M 201 older knitting machine from late 50's or early 60's. I'm not really sure what it is worth; hopefully someone can give me some insight. I have the original manual; It was carefully stored in a case, and well cared for while it was used, but hasn't been used for a while.

I also have a Duomatic 80 with the same scenario.
Any info would be extremely helpful!
