This is the majority of bullet guides used during World War II production. The first and second type bullet
guides marked B-8875 and B8875 are missing. Both are milled and have a narrow slot. The first
bullet guide on the left has all the characteristics of this missing bullet guides. The only difference is the
drawing number which is marked on the flat. The B8875SA bullet guide has the narrow slot and is milled. The next
bullet guide used was the B8875-1SA, it has the wide slot and is milled. The milled guide is next and just lacks the
drawing number. In 1943 Springfield added two relief cuts in the bend of the guide. Then they started stamping
them to save money late in World War II. The later post war stamped guides have a curved notch on the side. It
is thought this was done to add in removal and installation of the part.
