Pfaff 332 automatic sewing machine

Pfaff Automatic sewing machine 332 which was purchased by my grandfather for our grandmother in 1959. We still have the original manual, certificate of lifetime guarantee, part guide and the bill of sale (in german dated 5/20/59)

In addition to the sewing maching, we also have the foot pedel with plug, the original Pfaff tin with contains small parts and extra accessories and the snap out workplate.

Any general ideas of history, worth and value would be appreciated!! 

Thanks!
