After cancellation, that noble bird sat out in Palmdale until Reagan got into office and set Boeing to work on the B-1B aka The BONE.

To be precise, The B1 was designed and built by Rockwell International - much of it in my hometown, Columbus, Ohio. Rockwell then became part of Boeing Aerospace in 1996 as part of the large aerospace consolidation during the last few decades.

The B1 was designed and built by Rockwell International

Added precision:

Initially, the B1 design and fabrication was done by North American Rockwell at El Segundo CA (directly South of LAX in the same North American Aviation hangers and design offices that developed the P-51 Mustang, F-86 Sabre Jet and F-100 Super Sabre). Around 1972 the facility was renamed to Rockwell International where final assembly of the four B-1A prototypes was later completed.
