Interesting reply Nick,
would there be any photos of 1939 Khalkin Gol Mongolian era officers showing the pre 1944 (bastion/spearhead shaped) cuff insignia ?
I know they had various 1-3 or4 upward pointing chevrons in white , gold and blue.
Never know how many chevrons for each rank though - 2nd lieutenant, lieutenant, captain, major , colonel , probaly blue for junior ranks .
