Can pinned windage sights be fixed?

[RJW NZ]

I've been watching windage sights for a while, I want one with no serial number it for a restoration, and I've spotted one with three punch marks at the thread end of the leaf beside the knob. Is this a sign of being pinned and, even if its not, if I bump into one of these pinned sights can they be restored to working condition? thanks RJW

RJW, I'd go ahead and pick a working, operable windage adjustable sight as opposed to trying to restore a pinned rear sight work. Plenty of these sights show up on Aussie or U.S. eBay though never cheap.

As for trying to find a sight without numbers, why not just follow standard practice and renumber the sight to match the serial number of your rifle? If you don't like the previous serial number, you can always disassemble the sight and take a belt sander to the bottom and the old number will be gone in a jiffy. Besides , trying to find an original unnumbered pre-1915 sight in NOS condition might prove a total fool's errand. in 40 years of collecting I've never seen one. Ground ones, yes, brand new unnumbered, no!
