Would be hard to calculate, as there were several plants putting them out
and many assemblies were made in other plants and companies then shipped
to the assembly plants, Cessna produced tails, bomb bays were produced
at other locations and shipped. none of the books on the superfort
give the information you seek. as far as the ones I have anyway..
even when they left the plants, almost all went to mod centers to be
updated, to new standards, that could not be done on the assembly floors,
so that they were not slowed by the changes..
