Thanks for the link, they are a good shop, though postage might be costly all the way over to me. 
Unfortunately there are zero leather supply stores here, I would love to have a rummage in one  
 
The one I made is very sturdy as the leather is 7-8oz and with the extra lining its quite stiff. 
The next one I will use the same for the sides and 4-5oz  for the body.
