This is a photo of my grandfather in the late 1930s. He was part of a marksman club for the steel mill he worked for. I never met him, but I’d like to find one of these rifles if I could only figure out what it is. I know it’s probably not possible, but hoping some one can possibly identify it. I was told once that he was a fan of Marlin rifles, but that’s all I know. He is on the bottom right. Thanks to anyone who might help!
