Reid,
Well I don't have a lot, on this area. The DML kits seem to model this area well. MEREDITH was an original GLEAVES class unit, but in this area the BENSONs were similar. At the bottom are a couple of close-up views of the Aft Torpedo Tubes Foundation structure. Because the smoke uptakes and some of the fresh air returns were below this area and entered the main deck, an "arching" structural support was installed to transfer the load to bearing areas outside the intakes. (see the construction view aboard DD-427) The sides of the foundation then appears to be covered in sloping bulkheads with stowage lockers being utilized. Also, at least on the starboard side of many units (all?) a stowage cabinet/locker was installed attached to the foundation. (see attached view of GRAYSON in July 1942) At the same time (at least on GRAYSON) there doesn't appear to be a corresponding locker on the portside. There doesn't seem to be a single standard set of lockers added to the aft TT mount foundation. (see the 1945 plans for MAYO) In many cases, it appears that the addition of these various cabinets/lockers and stowage of other equipment covered the sloping sides of the TT mount foundation.
I have limited views of BENSON-GLEAVES class drawings from official Booklet of General Plans at the National Archives. The closest I have are for USS MAYO in 1945 rig and then I don't have complete plans of all aspects. I can't afford to buy scans of ALL plans I look at or have an interest in, but I take digital camera images and keep a "database" of them. If I find an overwhelming need for a set of scanned plans, I get them later. I have a modeling project dealing with USS MAYO, so she got priority.
I would suggest for MEREDITH as modeled at the time of her loss, to look at photos of her sister GRAYSON taken at Mare Island in July 1943 as your best guide. The first few units of the repeat-GLEAVES class (DD-453 on) also still had this foundation built in, there was too much work to take it out and replace with a more conventional deckhouse as was used on most repeat-GLEAVES units.
WARNING. The following deck plans apply to USS MAYO in 1945 ... structures and location of weapons won't necessarily apply to MEREDITH in 1942.
This view shows an inboard profile of "as built" contract plans of the midship area for the BENSON class (which was in general used for the GLEAVES class as well). For the GLEAVES class, a more conventional deckhouse was built between the aft stack and the aft TT mount.
