Hey all: Does anyone have a list of Lyman and/or Marbles Rear, Tang and Peep sight applications? I have a small box of about 20 Lyman and Marbles sights and accessories for which I have no clue what they go to. Most are Tang or Rear Peep sights and their bases. Based on the patina, they all look like 1920's - 1950's. Almost all are marked, I just do not know what those marks mean.
