At first I thought it was a Budd RB-1 Conestoga, but it's not, then I remembered the wooden wonder Curtiss C-76 Caravan.
First flight 5 Jan, 1943
the nose opened to load/unload cargo
3,000lb or 21 troops cargo load
two 1,200 hp P&W R1830-92's
200 mph top speed
There were reports of it being used in a combat zone, but was likley not true.
