Janyce,
Also before you plunk down your $$.¢¢ lift up the cloth under the presser foot. Make sure the needle plate and bobbin cover are there. I can't tell from the pics you posted. I do know that some on line auctions have had the bobbin / needle plate covered with cloth and unless you really look close you'd miss the fact the slide plate is missing.
They can be had, but then the machine won't look original, the plating on the aftermarket plates is different.
The spoked hand wheel is also a possible sign of a converted machine. Most of the factory electrics I've seen have the smaller solid hand wheel. The larger spoked hand wheel can adversely affect the running of the machine too. On one of my electric 66s when I'd back off the foot controller, instead of stopping the bigger wheel would keep on turning the machine. I swapped in a smaller solid hand wheel and the problem went away.
PS, love that cabinet.
Joe
