Earliest production guns had the yellow followers with the beveled front.
The yellow followers without the bevel came next.
The latest guns had the ES1 mags with the white followers.
I don't know the dates, if that info even exists, when one transitioned to the next.
What was original to a specific gun would depend upon it's manufacture date.
When was the gun in question produced? If it is very early or very late we might have an answer about followers.
