DId they just paint over the Plexiglas or replace it with armor plate when they constructed the gun nose Mitchell’s…
The G had its clear nose replaced with a shorter solid nose. But the J’s that were converted to gunships have a longer, but solid nose I believe.
The field conversions of the glass nosed were just painted over. But there was also a factory built metal 8 gun nose used also on the J model. Check the gun set up
Thanks guys
The G never had a glass nose. It was built with the shorter solid nose with two .50’s and the 75 mm cannon. The later H had the same nose but four .50’s and the 75mm. The top turrent was moved forward on the H also. Most of the glass nose B-25’s that were field converted to gunships were early C’s and D’s.
Edit
I meant that the G had the the typical glass nose of a 25 replaced with a solid. I did not mean to imply that the G ever physically had a glass nose installed.
Yes you would think the glass nose could never handle the recoil from all that firepower!
I dont believe that the .50s were physically attached to the plexiglass itself, and that the bores were far enough forward that the muzzle blast would not cause damage. (I have had a .50 fired over my head while driving a M113 on a few occasions and the muzzle blast is pretty pronounced, but will cause damage only within a certain cone shaped area away from the muzzle) Of you look at the package guns on the fuselage sides, there are reinforcements made to the aircraft skin in those areas likely to receive damage from muzzle blast. The biggest structural thing is the mounts for the guns inside the nose of the aircraft.
Early B-25 strafer conversion with overpainted plexiglass
factory built metal strafer nose B-25J
Field conversion overpainted B-25J strafer nose
The early strafer would have to be Pappy Gunn’s unit in Australia and New Guinea as it is before July-August 1943.
That would be the 5th Air Force, as General Kenney got him on his staff fairly early in 1942 and had him modifying the majority of their A-20s and B-25s into strafers.
Thanks guys. Who makes a resin gun nose convErsion for the Revell Be 25J
I want to say that Cutting Edge did, but it is OOP. Monogram did a hard gun nose J kit also.
and of course there is their field conversion glass nose kit as well
Stik: I got to tell you…I enjoy reading just about every damn thing you write about. You’re an incredible wealth of knowledge. =]
LOL! Thanks BV! I don’t know if this is a hobby or an obsession sometimes 
Cool!I wonder if I could make the 75mm/twin .50 configuration nose?
I think Accurate Miniatures did that one, the G. Monogram did the 75mm w/ 4 x .50s, a H as their original B-25 kit in 1/48. I can’t recall when it was last re issued.
Yes I remember the gun noses from the covers of the old Martin Caidian novels.
In 1/48, between Accurate and Monogram/Revell, all of the major production versions and field conversions have been covered for the B-25. B, C/D (and strafers), G, H, and J. The trick is finding which kit(s) you want for the Mitchell. Not a bad situation for us modelers.
Stik, we all greatly appreciate your freely sharing your "obsession " with us. It makes us all better modelers . I second BV 's comment about your amazing wealth of knowlege also.
