Thanks for post my photo Brian, I was attempting to locate any serial number range where a A marked trigger was used. Also keep in mind that there was both the A with serifs and the A without serifs too. The revision 2 triggers had the thin trigger then there was a thin trigger but unmarked but the A marked triggers have the thicker trigger profile. Most of the time you can spot the A marked trigger inside the trigger housing as enough of the A is exposed to view.

As a note: the thin trigger profile was also used on the early Model 1903 rifle before changes

How can you tell if the A marked trigger is SA or WRA? Or were WRA triggers no hole before Amola was used?

Not many Winchester triggers with the extra hole and A marked (I have one ) All the A marked Winchester triggers that I have seen have a larger size A which is also very thin and located to the rear of the trigger
