Generic OO Scale Whistles

I got two generic whistles for ya - one with a valve, and one without.
They've got a 1mm thick locator pin beneath the base, so drill a 1mm hole where you want it to go, and you're all set.

Sized for OO scale.

I don't know if I have to issue this warning but, these are literally 1mm thick, you've gotta handle them with care!
