This is deffinately a pic of a d5 and it has dive flaps still there.

Of Ju-87 D-5 in camouflage of winter on takeoff. Although it is this version which lost the air-brakes, the two specimens of the photograph are still equipped with it.
The Dora began deliveries in January 1942 to units on the Eastern Front. This had an up-rated 1400 hp engine and an increased bombload of nearly 4000 lbs (1800 kg) for short-range missions. Protection for the air crew increased with additional armor and replacement of the rear armament and its mount with an armored GSL-K 81Z turret mounting a twin-barreled MG 81Z 7.92mm machine-gun. The fuel system was similar to that of the R model with wing tanks that increased normal range to 510 miles (822 km). Underwing drop tanks extended the Dora's maximum range to 954 miles (1538 km).
Much effort was devoted to streamlining the Dora, one example being the repositioning of the Berta's massive chin radiator to positions underneath the wings and the oil cooler mounted in its place, but maximum speed only increased to 255 mph (410 kph) As part of this effort the landing gear redesigned to handle the increased weight in a trimmer installation which proved to be rather less sturdy than the Berta's.
The D-2 sub model was designed as a dedicated glider tug with a strengthened rear fuselage although almost any Ju 87 could be fitted with the appropriate hardware.
The D-3 featured more armor, protecting the engine, radiators, and fuselage belly as the Stuka was being used more in the the low-level attack role. The dive sirens which so discomfited Allied troops in the early years of the war were removed because they had lost their effectiveness.
Some D-1s and D-3s were modified as D-4s to carry a torpedo, but the torpedo attack role was better filled by the faster He 111H and Ju 88A bombers which could also carry more torpedoes. All D-4s were reconverted back to D-1 and D-3 standard without ever flying an operational sortie.
The D-5 sub model began to delete the dive brakes as unnecessary since they weren't used much. By mid-'43 when the D-5 was introduced the Stukas were more often used in the close-support role than as dive-bombers. Presumably this was due to the loss of total air superiority by the Luftwaffe so that the Stukas couldn't climb to the altitudes needed to dive-bomb properly without fighter escort, but ground-level attack missions could go on regardless. The D-5 also replaced its wing-mounted 7.92mm machine guns with 20mm cannon, had extended wings to reduce the wing loading and re-introduced the jettisonable undercarriage of the Clara to make belly landings safer.
As the aerial environment became less hospitable for the Doras they were transferred to night ground-attack units (Nachtschlachtgruppen) where their disadvantages were less apparent. The D-7s and D-8s flown by these units were modified from D-3s and D-5s respectively by the substitution of a 1500 hp engine and the addition of flame dampening tubes for the engine exhaust. These aircraft usually operated in flare-dropper/attack teams or under ground-based radio control, the latter referred to as the Egon procedure. The former method required one aircraft to drop flares to illuminate or silhouette the target so it could be attacked by the other aircraft. This was very similar to the method adopted by the British Fleet Air Arm for its night torpedo and bombing strikes, Taranto being the best-known example.
However some Stukas still flew by day as their special abilities required. These Gustav models were specialized tank killers, nicknamed the Panzerknacker (tank cracker) or Kanonenvogel (cannon bird). G-1s were minimal conversions from D-3s while G-2s were rebuilt D-5s that were much cleaner aerodynamically than the G-1. A pair of underwing Flak 18 37mm flak guns were mounted with 12 rounds per gun, the normal wing armament generally being deleted to save weight. The 37mm guns proved capable of destroying all but the heaviest Soviet tanks with their tungsten-cored shells. The Panzerknackers were extremely vulnerable to enemy fighters, but they flew on regardless until the end of the war.
This d5 (Werknummer 494083) has no dive flaps.

If ya really want to prove d3s had a dive siren then heres some books for yas.
