Help identifying a chietain model

Whistle

I have a chieftain low D and I wonder if someone will tell me what model it is,
as I’ve lost all track of these.

It’s tunable and the marking on the back is ‘KWL.’

Hi Jim
I think you probably know about this site but here’s a
link to the movies sectionhttp://www.kerrywhistles.com/dl.php?group=19#
Just scrol down to ‘Know your Cheiftain’
Hope this helps.
