Leather Doublet

Couldn't see anything like what you have pictured but this company has a fairly good rep. They may be able to custom make as well.

Museum Replicas , http://www.museumreplicas.com/museumreplicas/ used to sell the item pictured , but it's not on their website any more. they may have closed them out. the item number in their last print cataloge was 100462. you might try calling them.

Failing that, I'll second Ravenswood Leather they can make you anything you want, and the quality is great.
