OK then I'm guessing it's a late G conversion to strafer-nose. First to fly over the Japanese mainland since Doolittle?
That be it
Hawaiian Depot Modified B-25G of the 41st BG. Strafer nose, side gun pack on the right, rocket rails, waist windows, tail gun etc. 41st was the first B-25 Group to hit Japan since the Doolittle Raid.
Kind of a pretty version of the 25. I like the look better than the gun nosed J for some reason.
I came across a series of photos of this bird and crew on eBay. They were not labeled and it took me a while to nail it down.
You can see the rocket rails in this one
The open waist window and wind deflector mod was specific to the Hawaiian Depot
The side gun pack is visible in the next two.
