High Standard 12 gauge barrel question

[pax]

Anyone have specs. on the old high standard 12 gauges or a line on parts? I am looking at picking up a project shotgun but couldn't find anything definitive on them. I know the barrels are threaded into the reciever but does anyone have info on the torque specs on them? One part I am going to be changing is the barrel to a longer skeet/sporting barrel but can't find any barrels for sale or how interchangeable they are between the models. Anyone have the thread/pitch on them? Any links/info would be appreciated. I know the brand is a bit esoteric past it being handled by McQueen.
