Seamsright is brilliant! I would go with them if you don’t find anything stock.
I have one from 2005. 
Here is another Eous style.
Agreed, quality is top notch and they last forever. And you can get them in any color, style, hi withers, regular cut, whatever size you need…
Are they still in business? I tried to contact them last year as the 2 pads I have from them are finally worn out, and had no luck.
