Well boys, my USGI NM rear sight came in the mail today and I need your "insight" to see if I should return it.
It appears to be mostly original USGI, the finish is worn and yes you can tell it has been sitting a while. The right side of the base is marked "NM/2A". The aperature is also marked "NM". It is parkerized and does not appear to be cast in any way. That is the good news. Now for the "bad" news. The windage knob (right side) appears to be blued. There are no markings for windage on this knob. However I think there should be as shown in Duff's book on page 12. Also the knurling on the suspect windage knob is spaced closer together than on the elevation knob. What do I have here?
Shouldn't there be a cover that lays over the base also. Should that not be included with the assembly? One was not included.
Final question - How do you lock the windage and elevation when sighted in. The whole mess seems quit loose to me. Appreciate any help anyone can offer.
