Which one are you looking for? There were two sheet metal sights. There was the one that found its on to just about every model, then there is the Longhorn. It started on the late waffle tops, and continued on the Centerfires, up till the Osborn sight took over. If you have the Col.'s.book, its in there. When used with the Chuckwagon hood it gives a solid sight picture. There must be some funky laws of optics involved, because my Old eyes can still focus on them when not so much with an Osborne. 🤷♂️
