I can see why it's stuck. The edges of the spanner holes appear to be mangled a bit, making it hard to get a good purchase on the cups, I'm sure. Some people will say just leave a stuck fixed cup in there, but it may be hard to find a good BB match since I don't see any markings on the cups. Any markings on the spindle? It seems you actually have two adjustable cups--one removed with the locknut, and another (stuck) one without the locknut.
Have you weighed the frame? The BB shell looks like gaspipe.
I like your build plans!
EDIT: P.S. Where can we see more photos of your Masi?
