I purchased this sucker off of Craig's List for $125. It was a bit pricy given the condition of the cabinet, but the treadle mechanism and machine head are both in very good condition. They run freely and are relatively clean. It all needs oiling and surface cleaning though, and the cabinet needs some serious love. Somebody used it as a plant stand and did not water responsibly. Argh. Fortunately none of the water seems to have gotten down to the metal parts.
I haven't done any restoration work yet. It may be a while before I can really work on the cabinet, since I'll have to haul it to some place with proper ventilation. I'm going to try to get the machine and treadle cleaned and oiled in the next month or two so that I'll be able to try them out.
I love the decals on this machine! I've decided to name him "Phinx" after a character that a friend of mine made up. :D
