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

I know I'm late to the party, but here is the 1942 Army manual for disassembly of the shotgun, plus other models. I have used it to completely disassemble my Savage 720 and my Stevens 520 and will also trust it for my Ithaca 37's. It works very, very well. Very complete and easy to use if the directions are followed.
