I am trying to figure out when the changes to the New or With Swivel Arm Battle Grip took place. Especially on when it went from New to With.

Is this time line for the graphic more or less correct?

1983 - Large "New Swivel Arm Battle Grip" and Large "With Swivel Arm Battle Grip"
1984 - Large "With Swivel Arm Battle Grip"
1985 - Small "With Swivel Arm Battle Grip"
1986 - Small "With Swivel Arm Battle Grip"
