I recently cleaned up an old model 120 12ga pump for a friend of a friend and have had some trouble putting the bolt back together. This is the first Winchester I have taken down so I am not familiar with their actions.

I normally would not have taken the bolt apart but it was covered in reust and needed to be cleaned badly.

I thought I had the bolt assembled correctly but when I reinstalled it the bolt is extended and the action does not want to close properly. I looked online for the manual but I have not found a free download covering the bolt yet. Anyone have a source?
Thanks
