I do not think the RAC or RAPC ever wore the Royal Arms in Wreath as Paymasters & Schoolmasters became commissioned rank before the introduction of badge, and the RAC never wore them. I think you mean Royal Arms with Yellow border.
I think the Royal Arms in Wreath with Yellow Border was indeed meant to be for the First Class, Staff Sergeant Major RASC but was never used for that purpose.
Here are a few more examples of badge.
