Where's the physics package?

Nowhere in that pic. I vaguely recall the picture was showing all the non-nuclear major assemblies and military components that went into the system. I have never come across an actual picture of it.

I'm guessing that the actual shape of the physics package itself is in this case classified (primary-secondary-tertiary maybe?). Perhaps it installs directly into the bomb casing itself instead of into another casing first, making unclassified pics of not possible.
