Awesome! I sold one of those to Cathy(Mizkaki) they are awesome.
Want a copy of the manual?
Like the one I had, your's seems to be missing the belt guard, and you are also missing the spool pin it looks like. (although it is in the picture on the auction)
be careful about running it with the presser feet down, they were made with softer materials and that will quickly wear the feed dogs and or scratch the presser foot.
You did NOT pay too much for that. I've seen them sell for over $200 on more than one occasion.
