thanks for the pics. Now I'm going to do another flip flop on you. Shiny bits are shiny. That wasn't the image we got from your words. Now I'm doing to echo Micky2's words. "
With a bit of luck; try to find the spots where the paint glues part stuck, you might be able to force the parts free, cut it with a razor blade or thin blade knife."
Oil everything under the base that should move too and take off the faceplate and oil the presserbar and needlebar.
Looks far prettier than I expected. And congrats on the picture re-sizes.
