Whistle ID - Ó Briain?

Thanks fellas. I do vaguely recall acquiring an Ó Briain whistle back around 2002(?), which must be this one. It was shortly thereafter that I started playing a Burke Session D, so the Ó Briain hasn’t had much playing time since then. Interesting it’s now called simply the ‘Improved’ when apparently there were changes made to update it to the ‘New Improved’ as @Loren mentioned here. I’ll be curious if the current brass body version has a warmer tone than the nickel. I sold my Burke recently, so am adjusting to the very different playing requirements of the Ó Briain.
