The B25B normally had a lower Sperry rand remote controlled and sighted turret..while the B25B had them and were removed for the raiders...it was very ineffective anyway and was remove early in the war from all B25
Also the B25B normally had no tail guns..the A had a manned tail gun...the B just had a clear tail cone with no room for a gunner
The later B25s model did get a tail gun portion again I believe staring with the G model
Thanks for the help. I checked some of my sources again and they were accurate. I just didn’t pick up the correct understanding of what I read.
