'Whig' - You have a very nice model 1902 carbine sight.

Some model 1902 sight trivia:

Have you noticed on most 1902 sights, (RIFLE AND CARBINE), how the lines and numerals are slightly deeper near the eye-piece and shallower near the front pivot? This must be a result of how the leaf was supported, as the markings were 'rolled on', in the manufacturing process.

On a limited sample of four legitimate 1902 carbine sights (out of 1,000):

2 - Yours and markthenav's have the "Sgt. Peep" swing-up aperture (and two don't).

4 - have coarse serrations.

3 - have the 1903 knob.

1 - has the "C" stamped on the left-side of its base.

Such things will drive men mad!

(Attached photos - two views of my 1902 carbine sight and two views of a rare variant seen on the internet).
