In 1965, they revisited the concept as the B-71, but like the
earlier ones, it was never built. I've seen drawings of three
variants with bombs in the chines (like the YF-12's missiles),
a rotary bomb dispenser in the fuselage (inside the covers
of Crickmore's books?),


There are two drawings of that in Miller's "Skunk Works".
The bomb bay appears to be located at between 550 and 634 inchs back
from the nose of the aircraft, giving the bombs an overall length of
around 80 inches, and a diameter of 11 inches (although the drawing
looks like it says 71" for diameter, which makes no sense in regards to
the diameter of the fuselage shown.)

and a single large bomb in the fuselage.


That was supposed to be based on the warhead of the Polaris missile.
