O.K. #1 What time frame did the USMC sights and hood come about, and when were they removed time frame?

#2 I know that someone has a picture of what a new original 03 should look like or even a newly restored one?

#3 Rear sight leaf, is it calibrated for M1icon or M2 ball?

#4 I heard a rummer that a rifle when equiped with the USMC sites, the battle zero was changed from its 547yds to a more realistic 200yds? I have not had the chance too test this at 200yds yet, fact or wishfull thinking?


Thanks, Guys
