How to breakdown a 1943 Winchester model 97 trench gun??

I'd like to see some pictures of it myself, especially where the two halves join. If the military did specify they be built so as not to be broken down in the normal manner all that would be required is for the adjusting sleeve be advanced a few notches. There was no doubt a barrel wrench to align the halves and without it breaking it down by had would be impossible.
