This rear peep sight is an enigma to me. I have looked through all my husband\'s sight reference books, plus searched the internet trying to find this exact scope with no luck. I can give you measurements and condition, but that is far I can seem to get. If anyone can identify this rear sight, I would appreciate the help. With that said, this rear mount peep sight (base) measures 3.597\" OAL x .887\"W and features two holes forward the peep. These two holes measure .801\" apart (center to center). Elevation is marked 0-10. At first glance, this peep resembles most similar Marbles/Lyman/Redfield type mounts and appears to be of the same quality as these manufacturers. Most all original finish remains, no rust or pitting, bright shiny. Sight functions perfectly. (53-10948)
