Take this with a heavy grain of salt, but according to my measurements from the B-32 1:10 inboard profile drawing I've purchased from the Smithsonian the diameter of the Nose/Tail turret is roughly 46". This is the same reason I have yet to buy a 1:72 model of the B-32, they're all the same mold with the nose turret dwarfing the tail turret. From looking at it, I think the nose turret is the one that's wrong, as the glazed "chin" section looks to small compared to the rest of the nose. I could be wrong though.Question for AlanG: did your B-32 book ever come out? I'm looking forward to it!
General question for everyone: what was the outer diameter for the Sperry A-17 turret? I'm trying to build a correct 1/72 model of the B-32 but existing models are kind of suspect in that regard.
Did not know this manual existed. Might look into that. Would probably save me a lot of trouble when it comes to making the turret whenever I finally work on my B-32 3D model againT.O. AN-11-45C-19 Has the installation dimensions for the A-17 turret. There's a pdf available via eveilbay, but the guy is asking a bit high in my opinion.
Probably Emerson. Looks like the same one used on early P2VsI initially thought that the X/YB-24N nose ball turret was the same as in the B-32, but after reviewing some photos, they are very different. The B-32 nose turret was definitely the Sperry A-17 model. What manufacturer/model was the XB-24N nose turret?
The external differences I have observed are that the B-32 guns were closer together (6.5" center to center), they were located below the turret center, and only the center section of the A17 turret could be elevated/depressed. The entire XB-24N nose turret both yawed (azimuth) and pitched (elevation).
Here's the B-32 nose turret close up:
then the X/YB-24N nose turret also close up:
The third picture clearly shows that the entire ball (including the sides) pitches as one assembly.
I don't have any pictures that show a B-32 nose turret in an elevated or depressed position, but there are several reasons why I'm convinced that only the center section can pitch.
Hopefully it lacked the "pinching the ammunition belts" problem from the Sperry A-17, I recall it being a frequent complaint on the B-32.Probably Emerson. Looks like the same one used on early P2Vs
