The diagram is wrong. The leather should be threaded up over the stirrup bar from the back so the buckle is against the horse when it’s hanging freely, otherwise the buckle will be towards your leg when you pick up your stirrups.
The diagram shows the finished adjustment from the front. The buckle is not toward the riders leg. Peacock stirrups have the rubber band on the outside of the riders foot.
It is more than a little weird to show the the point of view from the flap side as the the stirrup hangs from the saddle instead of from the perspective of the human being who is going to look at the first image and thread the stirrup leather through the bar the wrong way, and then match their result as it hangs from the saddle with the final drawing. Good diagrams that show a step by step process are drawn from the perspective of the person trying to do the task. This is why the diagram is wrong.
I hadn’t realized the Peacock iron was also backwards. If we assume the Peacock iron is correct, then the assumption must be that this is the right stirrup and the buckle will be towards the rider’s leg. If this is the left stirrup the buckle will be towards the rider’s leg and the iron is on backwards.
Of course if the artist draws the diagram as if the left saddle flap is viewing it then yes, it is correct. Just why would anyone assume a process diagram was drawn from an impossible perspective?
If the person don’t realize their error by looking at it, they’ll probably figure it out when they start riding, and if they’re using regular irons they’ll be able to flip the stirrup over by sliding it off the bar. I was simply attempting to save Pippigirl the hassle.
I thought it was drawn strangely too.
