O.k .... I currently have been given a winchester pump model 12 16 gauge . It is completly rusted up and we are in the process of breaking it down and cleaning it up! ok here is the issue.. we have the diagram from the site. we are currently having a hard time removing #8(recevier extension) from 11 (barrel) it looks like there are an additional set of threads going vertically on the barrel.
