Luftwaffe tunic help

[bubi]

Hello, all, I have a Luftwaffe tunic with a name written inside of the inside pocket. I'm having some trouble on the last name and was hoping to maybe do some research on it. The officers first name was Siegfried but the last name I cant quite make out.
Any help will really be appreciated on this...

thanks in advance
Bubi
