a few "rare" parts for the 1903 rifle

I came across these parts at gun shows a few years ago, it is unusual to find these
1903 parts not attached to the rifle

first is the early blued open bottom rear sight base, appears to be a new part and
never attached to a barrel

second is the Rock Island rear sight leaf for 30-06 cartridges, note the square left side of
the slide (like the 2400 yard leaf sight) also without a top rib in backAttachment 87033Attachment 87034Attachment 87035

Neat pieces. All waiting for a rifle in need...
