I'm making this ammo belt using a kit I bought from 99centtaco. It contained undyed, precut pouches made of leather, undyed precut leather flaps, and a leather belt. The kit also contained snaps and eyelets too, but I haven't put them on yet.
99centtaco gave me full instructions on what other materials to purchase in order to dye and finish the leather the way he does. He also gave me instructions on assembly.
First pics here show the raw leather with Neatsfoot oil applied, then with two layers of brown dye:
