Neat source; I'm going to have to read through all that later.
I think the first few bombs took a long time to produce (we'd produced at least three in 1945, counting the Trinity test), but then we kept up a steady pace and ramped up production soon after (at least nine in 1946 by this source).

I'm assuming the 2 in 1945 were the ones they used (and not the remaining inventory), but I'm not 100%.
