Unertl Scope Battery Reset

[Cosine26]

I do not believe that the "dot" was ever incorporated in the original Unertls - at least not in those I have ever seen. I believe that they were added by "Tackhole" Lee who marketed and installed them as an after market feature.
From January 1957 American Rifleman Magazin e- ad for a Lee Dot



For anyone who is interested, the measurments of my original Unertl 1 1/4" are as follows:
OAL = 25"
Eyepiece = 0.850 "
Tube = 0.750"
Objective = 1.25" Mesured at the sunshade, but appears to ber same as objective lens.



FWIW
