Not the B-25, close enough. The two planes had much in common as far as sharing many different layouts for weapons.
Douglas A-26 Invader
Throughout its lifespan, probably housed a bigger variety of weapons, and configurations than any other airframe.
The one I was thinking of had 8 in the nose, and 4 (2 gun) pods (2 each outer wing), for 16. WW 2's version of the 50-cal (minigun)
It (other models) also had a 75mm+MGs(#-?), 2-37mm+MGs(#-?), 4-20mm+MGs(#-?), all 50s(#-?), all 30s(#-?), and almost everything in between, plus internal & external (GP Bombs, Rockets, Napalm).

You're up Vanir !
