Navy Rear Sight Oddity

Ronny,
how do you get those neat red lines in there?

But now that I played a small role in this discussion, I am going to throw a clinker in here. While looking at my sights, I noticed that there were many navy sights of all years that do not have machine marks in that tiny area. Indeed, many seemed to have been made with an ECDM (Electro Chemical Discharge Machine). These machine will sometimes leave bumpy surfaces of varying degrees. But given the machining of the time, I know that is not possible. Ok big guys, lets hear some theories on that one.
Ok, I take all this back. What I did was look at a navy that was restored. The restorer probably used an acid bath to remove the old bluing. The other gun was just dirty. After cleaning I saw the machining marks. Sorry about that!
