Mens Hair styles of the 1930's (Germany Austria)?

I play baron eberfield in the Sound of music, does anyone out there know of any good links to images of a good 1930's male haircut. I have grown a moustache for the part. Should I use hair oil and what sort?Mens Hair styles of the 1930's (Germany Austria)?
i'm thinking short at the back but with a long front section that is parted and combed back (held in place with oil perhaps brillceam?) Perhaps you could keep your hair so it is long enough to be slicked back (but the hair isn't actually long.)Mens Hair styles of the 1930's (Germany Austria)?
