Food for thought before going final on the design. A pair of triple Ds will eventually acquire the sag of maturity as the laws of gravity inevitably have their way. This may necessitate yet another corrective intervention with a boob reduction at some point to remedy complaints about a sore back/shoulders, cost/availability of custom bras, straps that dig in to a painful degree, etc. This could all impact negatively on your MILSURP budget in the years to come. Maybe just a set of slightly less ostentatious "Ds" would satisfy the need while avoiding some of these downstream complications.
If you are looking for a No1 MkIII Lee-Enfield with "full wood" these do show up on the EE fairly regularly.
