Shostakovich Lady Macbeth vocal score

[MyCatIsAChonk]

Hello - I have a vocal score of Shostakovich’s Lady Macbeth that I could upload, seeing as Shostakovich’s works are now PD in Taiwan. However, I’m unsure of whether this vocal score would be allowed, given that there is a German translation in the score as well. Here’s the details of the score:
Composed by Shostakovich (died 1975)
Libretto by Alexander Preis (died 1942)
Sikorski 2313 (publication date of this edition not listed)
Version 1932 (first edition)
German translation by Jörg Morgener and Siegfried Schoenbohm
Am I able to upload this to the IMSLP Taiwan servers? Thanks!

Does it say on the edition who did the Vocal Score arrangement?

No arranger is mentioned. The forward says "the rediscovery of the original version of 1932 ... and the coincident publication of it by SIKORSKI present the work as the author originally had it in view." This leads me to believe the reduction could be by the composer himself.
