Some questions about the differences then. As I understand it, on 14F70, the thermal protection system was (in order):

• Thermal protection tiles of composition:
  • High-emissivity coating (BK-12-18/15 and a different material)
  • (on the windward side tiles only) a variant of TINK quartz material
  • base of KSSK-150 pressed thermal insulator made of amorphous silica fibers on inorganic binder
• Felt
• Structural backing
• Separation layer (grid of ribs with pockets of air)
• Pressure hull

According to the drawing you posted, 7K-SM uses almost the same materials, but does not have the separation layer, with the felt and tiles attached to the pressure hull directly. This illustration, however uses the 7K-SM name and the 14F70 separation layer design. Is this a later version of the 7K-SM with the newer heat shield, or am I misinterpreting the diagrams?

Secondly, is 7K-M an alternative designation for 14F70? It pops up in a number of places but I have also seen it as the designation for a Soyuz modification from ~1972 (in Mishin's diaries for example).

Same question regarding 7K-SM and 11F732M, are they the same thing?
Karfidov mentions 7K-SM with the 11F732M designation, No.71 serial number and "preliminary documentation released in 1986" as a two-person ferry to Skif and Kaskad combat stations.

Do these illustrations show the early 7K-SM? (caption in RKK Energia 46-96 uses both 7K-SM and Zarya).

And lastly, is this drawing 7K-SM with parachute recovery or 14F70 mislabeled as 7K-SM?

I'd be more than happy to follow your lead if you just showed me *precisely* were to right click for an English (or much more better yet, German) translation, pretty please???

That was a link to the original source, and the original source is always in the language of the source documents — that is why it is the original source
