I have a New England Firearms Pardner in Mossy Oak Greenleaf camo that has the original non-removable sling swivels on it. This tells me that this shotgun probably came from the factory with a sling on it. Have any of you ever bought or had one of these with the original sling on it? If so, I would love to see a picture of it so I may can find an original sling and put on it. Any help would be greatly appreciated.
