Thanks for the comments guys, always happy to help.
Tk-938, it's a strip of 1/8" sintra cut 2.25" wide. I heated it up on one end, folded it over onto itself in a half circle, superglued and bondo'd it to close the gap, and then trimmed the sides at angles.
Things I'd do differently next time:
1. move the circle pieces of leather(with the snaps for the holsters) closer towards the middle because the snaps get in the way when I've got this thing on and I'm trying to push the cover piece over when taking the belt off.
2. use the accurate 4 ply 6mm leather cord, but I'm too lazy to braid it right now.
I did find this place in India that has it, but I emailed them and they replied with a minimum order of 500 yards at $170 per 100 yards. What would I do with 500 yards of this stuff. :confused
