Hi,
Long time lurker and have gained a wealth of information on the "03's. Recently my brother and I aquirred a Springfield 1903 from my step father. Typical NRA bought sporterized kind from the mid '40's, this particular gun dates around 1920 with a serial number 1215356 and a 1921 barrel.
What's odd is the Lyman sight. I found a picture of it in Brophys book on page 460, top three pictures. Not much is said other than it was tested by ordnance in 1910. The patent date on our sight is off by a couple years from the one in the picture.

I found a link to the Springfield Armory Museum that shows a rifle with the same sight but a different month date on the patent.

Springfield Armory Museum - Collection Record,

I'm wondering if anyone on the board has any knowledge of these.

Thanks
