Thanks for the input.
Maybe the uniforms give a clue and I didn't see any daggers.
I was told 1929 but wasn't Rohm in Bolivia from 1928 til 1930?

A small blurry picture here that has ss fuhrer written on the reverse.
I felt the officer on the right resembled Heydrich based on posture and what could be seen.
Just a guess and can't be confirmed because of the blur.
