I collect aftermarket sights and gadgets made for the 1903 Springfield. Some are works of art while others need a few more trips through the machine shop.
Many of these sights/gadgets are from home shops and others were commercially made for the retail market.
In the way of example, this is one of my favorites sights - a safety sight. It has an elevation adjustment only. The finish is a beautiful brown. There are no makers' marks. This is a very, very well made sight.
I will post pictures of of these sights/gadgets if there is an interest in seeing this old stuff.
