I didn't feel up to tackling the tricky and delicate work on the engines just yet, so I started on another area which needs modification before the main construction can begin, namely the ball turret mounting.
By the time depicted in the diorama (summer 1944), most B-24's in the ETO had their ball turrets removed, and the aperture plated over, although some Groups did retain them in at least a few, if not all, aircraft.
After studying photos of "Male Call", albeit mainly those few which show the aircraft after 130 missions, it appears the ball turret was removed from this aircraft at some point ( the Directive was circulated in late May, 1944), and she also received some "mods", for example, enclosed, glazed, waist gun windows.
Although the kit ball turret arrangement would look reasonable when retracted, the suspension yoke, fairly hefty due to being "operational" on the model, would be at least partly visible through the open waist gun positions, and would not look realistic.
Also, the framework and raised decking around the turret is incomplete, and sits rather too high, compared to the floor section around the waist gun positions (more on this area later in the build), where it should be a "step", slightly higher than the rest of the floor area, so I decided to dispense with the turret, and modify the floor area inside.
The "legs" for the floor/framework area were shortened by around 5mm, the internal mouldings for the gun tunnels were removed, and the fuselage insert aperture and tunnels plated over internally, using plastic card. These areas will be filled with "Milliput", and then blended and sanded to match the fuselage contours, and will then have the "blanking plate" panel line engraved.
The raised floor area, now reduced in height, has had the turret aperture blanked off, again using plastic card, and rudimentary walls added to the front and rear, as these areas can just be seen through the bomb bay access hatch and the waist windows.
Once the "Milliput" has been applied, set, and sanded etc, the interior area will be painted and the assembly set aside, as it is fitted from the outside much later in the build.
I'm not sure if the turret suspension/retraction yoke was removed when the ball turrets were deleted, although it makes sense that they were, so this part has also been deleted.
(Note that the B-24 in the Kermit Weeks collection, ex RAF/Indian Air Force, has the ball turret aperture plated over, but retains the suspension yoke. However, at one time this aircraft was fitted with a retractable radar dome, so this may be a "hold over" from that period).
I hope to make a start on detailing the engines sometime over the weekend, and meanwhile the pics below show the ball turret area mods so far.
