I think its a Heer cap converted to SS- Heer pattern chinstrap and what could be a green band. Taken in what year, do you think?
Hard to tell the year but I would opt for pre wartime but it really is a nice image and I would also say that it looks like a green band.
It looks like he has a ribbon for previous service in the Heer as (I think) I can just see the small eagle to the ribbon above his tunic pocket.
Thank you for the nice picture. These 'colored pipes' as they are called by the leaders of our little demimonde excite no end of pleasure.
A fine picture and Zeitdokument.
