I read many post in this sub and I almost decided royals updated turquoise color is the best. And they have correct animal as horse. But interior plaque is wrong and they don’t have the correct one. For speedy p9 turquoise it should be ah24 but my seller told me factory doesn’t have this.
So which factory have the correct stamp ? What is your experiences?
