Major General Nikolaj Bunin.

[Al-muell]

Unit 35240 was the Department "Cadre" of the Ministry Of National Defence. This unit stamp can be found on a great deal of these (if not all) to foreign service personnel.

Any Obituaries for Mikola available?

But is it normal that it is filled-in with 4(5?) different inks (1 for the awardee' data, one for signature, one for rank and probably another one for the unit number and general's name)?

I have searched for Mykola Bunin (using copy-paste Ukrainian letters, as I don't have Ukrainian keyboard), but found nothing.

I have, however possibly located hi address:

His last assignment was apparently in Odessa Military District, so its possible he stayed in the city after retirement, the birth date would also fit.

Also, Nikolaj m. Bunin indeed commanded 30th/74th ind. mot. rifle rgt.:
Полком последовательно командовали:
1 П/п-к (п-к) Бунин Николай Маркович – с сентября 66-го по декабрь 67-го.

The regiment was stationed in Neu Timmen, later in Cottbus, Germany.
Bunin was supposed to get his diploma in May 1967 in Germany, which coincides with the time he was a regiment commander.
