English stirrup leather buckle - unusual?

The closest I can see are these at Le Prevo

How are these attached to a saddle?  Does the stirrup go through the loop with the buckle, and the fixed loop go on the saddle's leather hanger; or visa-versa?

The small plain loop at one end slides over the stirrup bar on the saddle: nice and flat under your thigh. The buckle end, with stirrup attached within the other loop shown, hangs down. You can adjust by moving the buckle up and down BUT when shortened enough for the buckle to lay on top of the saddle flap, the back side of the tongue's attachment to the buckle rubs a groove in the flap. Bad design. There's a final additional hole in the leathers up near the stirrup bar loop so you can run them up for storage.

Thanks for the links and suggestions for other buckles! Now, the problem from what I can see is:

1. none of them would prevent the main issue I am having - the buckle tongue rubbing a groove in the saddle flap

2. some of them look to be brass - I consider this a weak metal and would prefer steel. Am I wrong? Or is brass OK? According to this site the tensile strength for steel is 460-1100- megapascals (MPa) vs brass at 325-625 MPa: https://structx.com/Material_Properties_003a.html

Silverd that's the one. Where are they available? Perhaps I just need to design a way to stop the tongue ruining the saddle flap after all....

I'm not an expert on this topic but I've made-up many stirrup leathers for clients and they have been happy with them so far.  I use Cast Stainless Steel Buckles in 1" and 1/1/8" wide from Abbey England along with their Stirrup Butt leather and Spun wound Poly Cotton thread.  Stirup butt is tanned specially to reduce stretch under high loading conditions. The Spun Wound thread is designed not to abrade and both are more expensive but both are very tough and I think work very well compared to the more popular straps today that are a composite design.  Today, most stirrup leathers sold in USA use a nylon strength member sewn between two layers of skirting or bridle leather.  The solid Stirrup Butt approach is traditional where as the nylon core is modern... Which I suggest is less costly.   Most of the leathers I sell are to replace nylon core style leathers that have abraded from the inside out.

As for the buckle I photo shared, it is an Abbey England Stainless Steel buckle in 1" that I quickly formed using simple tooling in my shop.  I did not purchase it in this form.   I  don't believe the stress of deforming the material into this shape will cause a problem with the material failing under load since the cast steel is quite malleable.  If you consider the actual loads your stirrup leathers see they are not that high actually.

For a rider that weighs 200 lbs and a 3g peak load = 600lbs.  There are two sides so you can say divide the 600lbs by 2 = 300lbs per side.  Convert to metric if needed.  

Re Preventing the tongue tip of the buckle from digging into the underside of the flap.  I would suggest that you look closely at the curved buckle as the way I see it a flat buckle may present more stress on the strap but I think has less profile which should translate into less protrusion of the tip into the underside flap.  This is suggesting that sacrificing the stirrup leather is better than damaging the flap.   Sanding the Tip down a bit to remove the sharp point I see on some might also help.

 I also think it would be something that could be prevented by using similar guard as is used on the Billet straps.  This is not a conventional solution and will add a bit more bump to the flap on the outside as a result but will protect the flap.  Make the guard from thin leather and replace it as needed.   

Hope this helps!

Just to say, I think leprovo may still be closed.    Might be worth checking on the website.

Do you think they will send some hides out to me as an attachment?

Thanks Silverd! Agree on the weight/force. Tho I have seen solid brass halter hardware break and the rest (nylon) stay intact, so I always want solid brass hardware because it will break. Of course, a horse is a LOT stronger than me

The part of the buckle that's digging into the flap is actually not the tip, but the heel end of the tongue at the back, where it attaches to the buckle bar. But again I can see a piece of leather there helping to prevent this - was hoping to preserve the simplicity of the design and find a buckle that doesn't stick out in that area quite so much!

Agree on the wrapped leathers. And in fact any tack wrapped or covered in a thin piece of leather - totally prone to wear out. I'd rather swap my leathers over to a different side and have them stretch evenly than have to buy new leathers every couple years.

Have you looked at the T bar stirrup leathers, instead of a buckle there is a T bar fitting , when in use a cover slides down over the fitting to help protect the saddle. Abbey sell the fittings. 

I've not used them but many people do to reduce the bulk under the leg.
