I'd created separate threads for a few of these instead of just updating here. I just finished two more, the blue Brother and the Necchi, two left, the Nelco and the Morse. The Nelco machine is actually finished but not tested as I have to rewire the connector for the wall plug and foot control (I have to solder, something at which I am not at all adept).
The Brother is a nice looking machine and sews as well as other 15 clones. The Necchi I had to test just on the workbench, and boy oh boy is it smooth and quiet; I think it's a keeper. I did remove the "wonder wheel" because the rubber on it was rotted and I do not have whatever cams or discs make it a wonder.
