Copeland Low D ....FS?

I spent a fair amount of time yesterday at the NE Chiff & Fipple gathering playing Walt Sweet’s new pro low Ds, and I REALLY love them. However, there’s no way I need two low Ds, so I’m considering selling my Copeland in brass.

Update-- the problem has been solved, and I await my new Sweet!

It is a very nice whistle I had a chance to play it yesterday.

I paid $385 for mine via eBay, FWIW. Thought it was a fair price.
