Where were the casings for those bombs made?
The actual pieces were fabricated among several contractors, apparently, so that no single contractor would know what they were doing. Below is for the LB casing.pic.twitter.com/jxpyfLRB8T

There was also a site in Pasadena where the casings and the timing device were manufactured.
-
Yes, Project Camel. I was unable to tell whether they manufactured the casings in-house or contracted them out (and then used them for experiments). They definitely fabricated explosive lenses there.
-
Yes, where the tunnel was dug to Cal Tech in the early 1930's. I doubt there is any paperwork saved on it.
-
The building had state of the art workshops and access to the best machinists of the era from Mount Wilson, where every telescope was created an original.
-
The tunnel to Cal Tech was dug for Einstein in the early 1930s to do developmental work, why it's the birthplace of the bomb.
-
Caltech certainly played a role in the project but there are many places that could lay claim to being the "birthplace" of the bomb. It was an endeavor that took place at a lot of different sites ("birth" is not the best metaphor for it).
-
Well, I think it obviously was very important to have the best physics mind involved who of course would of been Einstein, I think my statement is correct.
-
Not to mention, the concentration of the best physics minds in Pasadena at that time was unparalleled. Einstein talks so much about the importance of the inventive development of inventions.
