Old peep sight

[Stoney]

G'day fellas,
Could anyone possibly identify this old Redfield peep? Looking for model number and what years it was produced. Cheers.

Looks like a 102, these had different suffix letters for the rifle they fitted, ie: 102K was for the Krag-Jorgenson, 102B was for Savage rifles etc, they were made from the late 20's to the late 30's as a lowere cost option for their Model 100 adjustible sights.

I was hoping you would respond No1Mk3. You identified an Armstrong peep sight on my P14 post a few years ago. I am trying to get an idea of the age of the rifle I have. If I post a few pics would you or anyone else like to give an opinion? I thought the rifle is a 40's or 50' build. Perhaps it is earlier.
