Rear sight slide platinum line?

[Fred]

Page 456 Brophy, Springfield 1903 rifles "first type leaf graduated to 2,400 yards has first type drift slide with a vertical platinum line running through the peep-hole". Guess you have a type 1 slide.

Sorry, that refers to the slide with the peep sight on it, not the battle sight notch. Two different things.

Here are some additional photos of my sight with the white linedscn1355_0017.jpgdscn1361_0021.jpg

I have one that I found at a gun show in South Dakota.

I should have mentioned that I tried to hunt elk with mine and the white line made it difficult to sight through the peep. I assume that's why they were discontinued.

The second one looks like the notch was also opened up some.

I imagine it made for more user friendly mod for anyone over 30.

I think that the reason this particular sight notch was opened up is that it is the USMC rear sight which would have been "opened up" to accommodate the wider USMC front sight. It is that way on my Marine Corps rifle. Also the area of my widened notch is all filed down to expose a wide "line"-- certainly not platinum. If you want to see pictures of the rear sight on my USMC rifle to see what I'm talking about, search this site with the number 1009445. You will come up wth a thread containing a link to photos of my rifle and its rear sight.
