the 1941 jpg plan I sent you should be good for that.
David, thanks so much for the '41 drawings! I really appreciate it. Your 1945 Pennsylvania model looks really, really good!
The drawing you sent is particularly helpful with the features of the navigation bridge and rangefinder/air defense platform. Thank you very much!
Accurate 1941 Pennsylvania drawings have been difficult to find generally, in that in every drawing I have had access to, the position of certain deckhouses does not match photos of the ship. This is particularly so of the flag bridge, the lowest, largest level. While the shape of the decks matches photos, the shape and position of the deckhouse does not.
Alan Chesley's drawings of the ship as it appeared in 1935 don't show the tower's individual bridge decks, just an overall plan and profile view, but what is visible does match photos making this a very important drawing for the design.
Careful study of photos indicates that Pennsylvania's flag bridge deckhouse is a compound structure, with an inner six-sided deckhouse enveloped forward by two dog-leg-shaped bulkheads forming an outer, expanded deckhouse that abuts the rear of the armored conning tower. It is similar, but not identical to, Arizona's. The plan-view drawings of this deck I have had access to show a simple, big room, much wider and simply shaped than what appears in photos.
The two photos below (thanks navsource) show how the rear-most part of the flag bridge deckhouse recedes under the platform above which is supported by several stanchions. It is the exact location of the footprint of this deckhouse that I am after. I
think that the inner six-sided deckhouse footprint matches Arizona's. Please confirm or deny.
