Oh no!
I'm tender about messing with whistle tenders.
They keep my 2 Evans auto loaders full of heavy die cast from string lining and spilling coal and water all over!
Then again, you did slip an Adriatic and a gunfighter car onto the thread, 2 of my all time favorites, so I'll forgive you for trying.
(And I do have plans for similar, but only if I find a loose whistle cheap enough before I find a tin whistle house )
