Can anyone identify this peep sight?
Recently picked up another Oberndorf Mauser Model M in 30-06. It has a receiver peep sight that mounts on the bolt stop like a Lyman #35, (no drilling and tapping), but it does not resemble the Lyman in any other way. I can find no manufacturer's markings on it. There is also no indication that any open rear sight was ever installed so the peep may be a factory installation. I know Mauser kept a supply of Lyman and other sights on hand for installation at customers' request. I have another very similar Model M, the same caliber, with a serial number only four numbers later, so they were probably both made the same day in 1923. However, this one has a more conventional Lyman #35 sight. (last photo)
