Hello,
I have inherited this Pfaff Industrial machine.
As you can see in the images, the manual that came with the machine lists the Pfaff 491, 471 and 474.
The machine is a Pfaff, and runs on compression from an Efka Variostop motor.
The machine was running properly according to the last owner.
This machine comes with the table and manual.
For local pick up only. Knoxville, TN
Please email brigid.ko(at)gmail.com with any questions, if you would like more images, etc.
Thank you!
