https://bulangandsons.com/bs-signature-handmade-leather-nato-straps/ Slightly different but very similar. Have a search on Google for "Distressed leather NATO", go through the images and you should find some other links.
Bulang and sons is great. Good quality and feel. If you like the style in the picture that is a Zulu strap, very much like a Nato but with rounded loops instead of square.
I don't think they are called the zulu anymore (at least I can't find any on the site), but I'm assuming this is the closest thing - https://bulangandsons.com/product/bs-signature-the-lumberjack-brass-nato-strap-20mm/
No, look under leather Nato. They are there. Maybe B&S doesn't call it Zulu. Just look at the shape of the Rings, if they're sqaurish it's Nato, of round it's a Zulu. So forget about the name and look at the pics. I just saw them. They're also on the curated watches.
