Finding a source for those functional, hinged brass cantles is the hard part. I know Lamar Britt was talking to a friend of his about having them made at some point, but I think that fell through. Donnie Shearer (themadpiper.com) makes his own by hand, and it's pretty labor intensive. His sporrans are wonderful, but expensive, and the majority of the cost is in the cantle. I'd keep checking the House of Labhrain site as they seem to be one of the few places that has them on occasion. I saw one -- once -- on Ebay and still kick myself for not buying it.
