What a great find, price was good too. I have the same machine. The wonder wheel attachment is what makes this a collectible machine for me. You do have at least one part of the wheel missing. I will go trough my manual and try to see if you have all of the other parts. A manual is a must for excellent operation of this machine, they come up on ebay all of the time. I had to fabricate the part you have missing, as mine was missing too. It isn't hard to do.
PM me if you have any questions I will try to help.
