help with head issues

[ringo5589]

I picked up a sharpshooter the other day it is in pretty good shape other than some idiot pulled the trim off around the back box. I was wondering if someone could send me some pictures in detail of how the back glass is held in and maybe some measurements so i could rebuild it back to spec. This is my first GP so i am not sure how the back glass goes in or out.    Thanks in advance

I have an Old Coney Island, which has the same back box as the sharpshooter. Is it the complete wooden frame of the front of the box that's missing?
