The leather color is very hard to find. Loanstar and Bobamker are the only current makers that I know of. Mine was made by Ladysewforus but she hasn't been around for a while.
The difficulty of finding the leather is one of the biggest reasons why there are so few makers. But if you want a good looking screen accurate Jango the vest is a critical part and it is worth the cost and wait time. I would suggest patience and diligence in sourcing the vest.
