I have three sporrans. I got my first in the mid-70s. It was a simple brown day sporran with a brown strap, probably from the British Shop in Buffalo, and by mail. And the first thing I did with it was get my black leather dye and dye it black. I still have it, and I still prefer it that way. Nothing to do with the kilt hire industry though. It didn't exist anywhere I could conceivably even be influenced by it.
