Does anyone have any information about this variant of the Stuka? How about any drawings or pictures?

Night-harassment variants[edit]
The Soviet Air Force practice of harassing German ground forces using antiquated Polikarpov Po-2 and R-5 biplanes at night to drop flares and fragmentation bombs, inspired the Luftwaffe to form its own Störkampfstaffeln (harassment squadrons). On 23 July 1942, Junkers offered the Ju 87 B-2, R-2 and R-4s with Flammenvernichter ("flame eliminators"). On 10 November 1943, the RLM GL/C-E2 Division finally authorised the design in directive No. 1117.[73] This new equipment made the Ju 87 more difficult to detect from the ground in darkness.

Pilots were also asked to complete the new "Blind Flying Certificate 3", which was especially introduced for this new type of operation. Pilots were trained at night, over unfamiliar terrain, and forced to rely on their instruments for direction. The Ju 87's standard Revi C12D gunsight was replaced with the new Nachtrevi ("Nightrevi") C12N. On some Ju 87s, the Revi 16D was exchanged for the Nachtrevi 16D. To help the pilot see his instrument panel, a violet light was installed.[74] On 15 November 1942, the Auxiliary Staffel were created. By mid-1943, Luftflotte 1 was given four Staffeln while Luftflotte 4 and Luftwaffe Kommando Ost (Luftwaffe Command East) were given six and two respectively. In the first half of 1943, 12 Nachtschlachtgruppen had been formed, flying a multitude of different types of aircraft, including the Ju 87, which proved itself ideally suited to the low-level slow flying needed.[75]

How long were the used for, how many were produced, and were they effective? Any perspective from the Soviet side about these? Any help is appreciated.

Wojtek should be along any second now.

Ju 87's in the NSGr's were D-3's and D-5's sometimes referred to as (N)'s. there were no R's night raiders. also the the D-7 and D-8's never existed that is incorrect.

 

[Denniss]

It's not impossible they used Bs and Rs for night training while in-unit they had Ds.
D-7 and D-8 were existing, just not as production model. They were older models upgraded to D-5 standard + night equipment.
