F190 is for my reference.
The movement marked E.N. Welch. It's sold for parts or repair. One if the springs is broken. The other spring seems to be ok but has some rust on it. It's backplate measures roughly 5-3/16"×3-9/16". It's Untested and needs to be gone through. Good for parts or repair. Comes as seen in pics. Any questions just ask.
