Fascinating find. Well done documenting that.
They look fairly sharp to me, but with narrow DoF. I'm surprised it seems so narrow given that you were using f/40 for the first and f/22 for the reworked one. (The second and third images in the top post show up as private over at Flickr). Are you cropping much?
I much prefer the rework. The versions in the top post seem very dark to me. It isn't exactly under-exposed, because the histogram stretches right up to the top. I think the highlights are being protected. But as a result the top half (and more) of the histogram is extremely flat, with the bulk of the pixels falling in the bottom third of the histogram. It seems to me that for all of them the Exposure could beneficially be raised by a complete stop or so and the images then adjusted from there with the other sliders in the Basics section.
