Here it is with the spoked wheel installed. Somehow it just looks at home on it ;-)

It looks very good! I have a 201K with a spoked wheel and I have been thinking about the exact oposite convertion ;- ) Did you get a chance to find out the differences between your two model 66s?

Lol! To each his own! No I haven't gone through the other one yet. But I will. Thanks again for your help.

The smaller solid hand wheel was made for a reason and I'm sure there are advantages too it with the electrical set up. There larger wheel gives a bit more punch to the needle when keeping a nice steady speed. Either way, I probably will keep my 201K as it is. I'm hoping to find a 201 with the art nouveau decor on the chromed plates; they look so good. Most 201s have the smaller wheel, not sure about the 66s, most early ones I've seen have been in treadles.
