Mars 2MV-3 No.1 aka Sputnik 24 Lander? Options

[sittingduck]

I am working on a graphic which displays simplified 3D models of all Mars exploration spacecraft to date.

This will give you the idea: http://i.imgur.com/e4amxAD.png

But I've run into a problem; the fifth spacecraft launched at Mars was "Mars 2MV-3 No.1 aka "Sputnik 24" which was apparently a lander (represented by an ERROR in the graphic). I cannot find any documentation concerning the type or appearance of the lander, or whether it flew with a flyby bus similar to the 2MV-4 probes.

If anyone has any idea what sort of lander this was (I expect something like the Venera 4 entry probe) or whether the flyby bus was present/similar to some other probe, the help would be appreciated. I find there is a saddening lack of information regarding this first landing attempt.
