Let me suggest that such a family heirloom can and should be worn with great pride during the ceremony. It appears to be in wonderful condition... and I wouldn't be too quick to make it new again either. What you have is a precious bit of family history. Let it "shine" on its own complete with blemishes. Get a new fluffy white sporran to wear afterwards if you want somwthing shiny to show off. Before you do something to it you might regret, perhaps talk to someone from a museum that might be abl to advise you about preservation, storage, or even restoration.

The sporran is awsome and something wonderful to pass on to the next generation!

...and best wishes for your future wedding.
