I have the very same sporran, it has worked for me for many years. The only problem with it is that the pocket is a little small to hold what I want to carry, I had to buy a smaller wallet to fit in it.
I had a few different sporrans but I wanted something unique so I went to Tandy Leather company and purchased some leather and the tools that I would need to do the task of making a sporran then I contacted Moscow Hide and leather in Idaho and ordered some different skins.
I made a great sporran from a black bears front paw complete with claws and all of this for under what one of the more expensive sporrans would have cost me AND I still have plenty of leather to make more when time permits.
I was also able to make my own belts ans straps for a fraction of the cost. Tandy Leather carries both brass or chrome buckles to finish them also.
Just my suggestion.

Chris.
