Let's have a try with a lot of guess work and speculation. Dimensions can be estimated very
roughly by the size of the engines and to a lesser extent by the crew seats and waist gun positions,
which look very similar to those, installed in the Privateer, although looking slimmer here. Another
clue may have been the live rafts, but I couldn't find dimensions for them. Surely it would have been
a large aircraft, estimated length around 26m, span 35m, so in a class with the PB2Y Coronado, but
still smaller, than the Boeing XPBB-1 Sea Ranger. A detail not shown in the cut away is the cockpit.
Following the style of the (later) Tradewind, I've chosen a closed cockpit section with windows.
Would a framed glass house à la B-36 be more plausible ? Really don't know, here my decision was
based more or less on taste only. The bomb bays and their size were taken from the Coronado,
what puzzles me is the mention, that they were placed behind the rear spar, but maybe main and
rear spar were spaced very close.
As always, a drawing deduced from an perspective picture is rated as source grade 2 at best, no
guarantee for the correctness of dimensions and proportions !
