Anyone Know Anything About River Mallard Custom Calls?

[lucoca4]

I came across some River Mallard Custom Calls for sale and they look really nice, I was wondering if anyone has ever blown in one or know anything about them?

I blew one 2 years ago at the IWA and they aren't bad. The guy was pretty nice that was at the booth.
