Not sure if LB-30s were built at Willow Run also like the B-24 was...
No, there weren't any LB-30's produced at the Ford plant, as the LB-30 designation was only applied to a small number of the very early production B-24's built by Consolidated for export - "LB-30" simply being a different designation applied to the first production models of the YB-24 and B-24A, which were initially to be built for the French, but following the collapse of France were redirected to the British (LB-30 vs. B-24 is like the designation Hawk-75 vs. P-36 or the P-322 vs. P-38 Lightning).
The CAF's Liberator was one of those which were built to B-24A/LB-30B/Liberator I standard (all pretty much the same thing, however you want to call it), fully armed and with bomb bays. It was completed/first flown in early May 1941, but it never left the US. Under USAAC Ferry Command, it was sent to New Mexico to train RAF pilots (still in its bomber configuration, and painted in full RAF camo/roundels). It was heavily damaged in a landing accident in late July 1941, and given the amount of work that Consolidated would be tasked with repairing it, Consolidated decided to take the opportunity to rebuild it as an experimental transport. Following the repairs and modifications, it didn't fly again until almost exactly a year later, and would be put to work by Consolidated through the rest of the war (despite still being owned by the British Air Command, though Consolidated covered all of the costs). Although it was never classified as a C-87, it paved the way to the production of the C-87 variants, having proved the viability of such an aircraft.
