German uniform information...

Can anyone assist me in getting some info on the uniform below? Perhaps direct me to where I can decipher rank, unit and such?

 

To my untrained eye, there is unfortunately not much to see...

It appears to be the early German M35 Waffenrock (probably used for "official" picture). Rank seems to be Schütze, I see nothing that hints at any higher rank. No clear unit emblem visible. There appears to be a (possible unit-)number on the epaulette, but it is not clear what number it is. Also, since it is not in true color, it is impossible to determine branch of service.

 

Thanks for the info!
