Photos need help to identify B-24 '2-D-4' and unit

[Spartan54]

I have a 1940s vintage red-bordered Kodachrome slide of a B-24 with titles '2-D-4' on the nose but the tail is cut off and don't know its serial no. I would also like to know the unit it belonged to. see attached. Judging by the terrain it looks like Thule Greenland. Any suggestions?

Interesting. Looks like it has sealed-window waist gun positions, and an Erco nose ball turret. Could very well be an late model PB4Y..... Navy.

Yes it is a PB4Y-1 of USN. The markings indicate that it is from VD-2 (VD-1 to 5 plus VMD-154) were photographic recce and mapping units.
