Identification & Front Sight problems

[kress]

Hello

I am new to this very nice forum and this is my first post.

I've recently acquired my first Luger and would really like some help to identify it. I know that it is a DMW from 1917, but that's it.

Also the front sight is loose and can be moved even more to the left than shown i the pictures. I cannot move it more to the middle.
