Did B24D's flying in 1942/43 in the PTO have a non-turret open rear gunner station? Not the turret version I always thought they had.
 
Been through 7 books, 12 to go and nada. Of course, that's not to say there weren't

EDIT; Cross posted with Syscom3. I did see a photo that looked like the ball turret was removed and it looked like twin MGs sticking out of the hole. I'll have to go find it again and check to see if it had a rear turret

The ball turrets started to appear midway through the D types during 1943...up to that point, there was a "tunnel gun" position...

To get a good idea of what an early type (pre-turret) looks like, check out the CAF's B-24A. It has the "tunnel gun" position and the single .50 on a pintle-mount in the open tail position.

* Here, I added this link to a page that shows excellent detail of both the tail position and the tunnel.

Picture 1 shows the standard tunnel gun mount used on early B-24Ds located in the hatch to the rear of the waist gun position. By Dad, a gunner on them said you couldn't hit crap with it.
Picture 2 and 3 show the tail gun installation you asked about. I do remember hearing somewhere it was a modification on some B-24s in the Pacific.
Picture 4 shows the manual gun installation replacing the ball turret. I believe this was also a modification in the Pacific. It's very hard to find pictures of it. I remember seeing an interior picture of it somewhere but I could not locate it in my files.

I hope this is of interest. B-24Ds were nominally built with the Consolidated A-6 tail turret, as was the preceding B-24C, but, like Dave stated, early production B-24Ds had the tunnel gun under the belly like the 'C model. It's possible that turrets might have been removed after delivery or even delivered before the turret had been fitted on the production line. RAF Liberator IIs - the first Liberator variant fitted with turret armament - were delivered unarmed to the UK and were armed on arrival. Info on the Liberator II: Consolidated Liberator II B-24C: Consolidated B-24C Liberator and 'D: Consolidated B-24D Liberator

The RAF ordered B-24Ds directly from America before Lend Lease and these were designated Liberator IIIs. In Britain the Consolidated tail turret was removed and a Boulton Paul four .303 gun turret fitted in its place, as the Liberator II had fitted. See here, from this site:

The four gun tail turret on this 120 Sqn GR.III can be made out:

Later Liberator IIIs received through Lend Lease kept the American armament and these were designated Liberator IIIAs and were initially indistinguishable from B-24Ds before modification in Britain. The Liberator II, however was delivered to Britain unarmed and BP turrets were fitted in the tail and mid upper position, but some went into service without an aft turret. See here:

Here's an interesting pic of a B-24D tail section without turret fitted. This aircraft B-24D 42-40387 crashed in Queensland, Australia:

The earliest B-24Ds had a Bendix remote ventral turret, the same as on B-25s. Those with the turret had them removed and replaced with a tunnel gun, which was also introduced in the factory and remained so until replaced by the ball turret in late production Ds. The Hawaiian Air Depot modified B-24Ds for the
7th 13th Air Forces, by moving the tail turret to the nose, adding manual tail guns and ball turrets.
5th AF aircraft retained the tail turret, added a turret to the nose and ring mounted ventral guns.
J,L,and M models had the ball turret replaced by the ring guns. 7th 13th AF Js replaced the tail turret with manual guns, or power boost M-5 or M-6 mounts. They usually retained the ball turret.

Great info - this coincides with what was depicted in the movie. Zamperini flew with the 372nd BS, 302nd BG, 7th AF.
 
Ok, I'm going to nit pick. Just saw the movie. The single tail gun is strictly B-24A. The waist gun position don't have wind deflectors, true for very early "Ds" but not 1943. Theater greenhouse nose
B-24Ds usually had four nose guns, two, mounted high and low in the nose piece and two cheek guns. Ball turrets were installed by the Hawaiian Air Depot at the same time as nose turrets. Greenhouse "Ds" had tunnel guns. Having said all of the above, a much better than average depiction.

Post script:

How did researchers allow an A/C with prewar red disc in star insignia appear in Louie's homecoming in 1945?
