The book "Junkers Aircraft and Engines 1913-1945" by Anthony Kay (https://www.amazon.co.uk/reader/0851779 ... y=ef%20131) notes that the Ju 287 V5 and V6 were to be prototypes for the Ju 287B-1 and Ju 287B-2 respectively, while the V3 and V4 were to be the Ju 287A-1 and Ju 287A-2 prototypes. Drawings of the Ju 287B can be found at this link:

There is an article about Ju 287 on the excellent site http://perso.wanadoo.fr/prototypes.com/index.html

http://prototypes.free.fr/ju287/ju287-1.htm

For those who do not speak French here's a summary:

Ju 287 V1 with 4 Jumo 004B (testbed with He 177 fuselage, flown in 1944)

Ju 287 V1 (identical with Ju 287 V1, but not completed)

Ju 287 V3 with 6 RD-10 (Jumo 004B) and Ju 288 fuselage (flown in 1947)

Ju 287 V4 (identical with Ju 287 V1, used for static tests)

The drawing below represents the EF-131, a slightly modified Ju 287 V3

Ju 287 production model with 4 He S 011 (not completed)

EF-125 - projected development of Ju 287 production model with 2 Jumo 012 or 2 BMW 018 (not completed)
Image

EF-140 - russian built EF-131 with 2 RR Nene (flown in 1948)

The Ju 287 production model with the 4 Heinkel Hirth HesS 11 turbojets was the Junkers Ju 287B-1, which had the same glazed nose section as the Ju 287 V3 and Ju 287A-1/A-2. The machine with the caption "Ju 287 production model with 4 He S 011 (not completed)" is actually the Jumo 004-powered Ju 287A-2, which had six engines (two fuselage mounted, four in two wing-mounted pairs).

Here are photos of the Junkers Ju 287 V2 (code RS+RB) being hidden in the forest at Brandis, as well as a 3-view color drawing of it.

You'll note that the second Ju 287 prototype, despite being similar to Ju 287 V1 in being made by cobbling parts from different aircraft, differed not only in having 6 turbojets and a slightly lowered horizontal stabilizer, but also light grey colored trouser pants for the nose wheels and the inward angle formed by the landing gear support struts (as opposed to the outward angle formed by the landing gear support struts of the first Ju 287 prototype).
