Gunsmithing Stevens Model 520

[Halfnutz]

Does anyone have a link to where I can look at a schematic for a stevens model 520 or 520A? (Numrich dosen't show thiers.)

I have a friends "Ranger Repeating Shotgun" I am cleaning up for him. He claimed it had extraction/ejection issues. I need to see what the ejector should look like. This one seems a little worn but doesn't appear to be broken. It does eject but not 100%

Any historical info would be appreciated too. I have found some but it is spotty.

This is a neat old shotgun. Wife has camera or I would share a pic.

Thanks all.
