The Bounty Hunter's guild is working on the Zam Wesell CRL. Currently, one member submitted a draft, and I've printed it out for reference as well as all the things I've found here. If you want to take a look, it's under prequels BH CRL's. http://thebhg.net/forum/
It's halfway down the page and pretty long. Can't miss it.
Or here is the cummberund info (without accessories info):
Cummerbund and Accessories
- Cummerbund is made of leather or similar material.
- Cummerbund is lavender in color and roughly matches the other purples used in the suit.
- There are 4 rows, separated by stitching in between the rows.
- The cummerbund is padded.
- It is two separate pieces, laced up and connected by black lace hooks or speed hooks in the back and on the right hip under the holster.
