Pfaff treadles being as rare as they are in the U.S., I didn't have a spare, so I put this machine in a Singer treadle. It is an incredibly smooth-running machine, a joy to treadle.
More information here on this model, showing an original handcrank machine. This one was originally an electric, with an external motor on the back, and the silly little plastic handwheel that the model 130 came with as well.
I've replaced the original handwheel with a heavy, spoked wheel from a Singer machine, to give proper momentum when treadling. And it looks a whole lot better, too.
The faceplate and upper tension mechanism on this 30 are also the same as those on the 130. The 30 is straight-stitch-only, the 130 one of the first zigzag machines (starting about 1935).
The finish on the back pillar and bed are chipped significantly from the motor, which had been replaced (badly) at least once. Otherwise, the finish is in darn good shape.
This machine is serial number 5920 182, dating it to 1957.
Underneath view...
The model 30 has a side-loading bobbin, versus the 130 with it's front-loading bobbin... although the slide plate is on the side on both models.
Several extra feet come with this machine, a narrow hemmer, a cording foot (?), and a zipper half-foot with a hole in it to accommodate a quilting guide. Bobbins, needles, and a seam guide.
