The bottom bracket should come out when you remove the screw at its bottom. Yes, bottom bracket shells and other frame parts were manufactured and sold to frame builders.

When the bottom screw is removed the bb wont come out of the frame as far as I can tell that screw sets the tension on the chain, it's almost like the two bb are pressed together but that wouldn't make any sense, can't tell unless I probably remove the paint from the bb to see what's under the paint I'm hoping that they are perhaps screwed together, would that make more sense on a install such as this...
