Early prototype rear sight base?

[butlersrangers]

These unused & unfinished Springfield Armory sight bases have been around forever.

That they shared components with the model 1902 Krag sight is unmistakable.

Does anyone know what they were really for? I have seen mention of 1900 or 1901 Springfield prototype? They are made of steel with an ID of .798 inch on the barrel rings, which is too small for Rod-Bayonet 1903 Springfield.

Pretty cool machine work! They look new, but, are old. (A Krag 1902 sight leaf inserted for drama)!

Hi BR,

Ran across this listing on Gun Broker for a 1903 Springfield Rod bayonet rifle. The sight base looks kinda familiar.

A M1903 barrel will screw into a M1902 receiver
, but the diameter of the M1902 barrel could have been small enough for this base to fit. I believe I have seen a picture of a pile of M1902 ( AKA m1901 ) barrels in the white with the sight bases installed.
