Hopefully, there's someone out there who loves their Burke, but would like to have the brighter look and sound of aluminum. But, to sweeten the deal, I'll throw something else in to go with my aluminum D... Extra money? I have a Bb Susato whistle that I'd be willing to add to the deal (and some money)? One other option that I'll throw out is glass work. I'm a glass blower, and make... um... functional art glass pieces, like this:
The thing is... I really love this whistle, and the only thing I'd change is the material of it. I'm really not interested in trading for anything else.
