https://www.jean-rousseau.com/shop/nato-strap-khaki-cordura/686215-cordura-khaki/ OEM supplier. Can't remember if the 45th color was 'Khaki' or Brown, but you can reach out to them and ask for photos which they will gladly provide. You can customize it too....
There is one for sale here on OF. https://omegaforums.net/threads/omega-20mm-nato-„olive“-45th-11-apollo-color-new.106987/
