Whammy-Diddling World Championship

I have lost (sorry misplaced sounds better) the Whammy Diddle Box. Know where it should be but it’s not there. Something at the back of my mind tells me someone was interested in it for something but for the life of me I can’t remember (it’s an age thing)
If anyone can shed any light on this please let me know asap. It’s a hand made brown wooden box approx. 15″ x 15″ x 4″. Last used in Vineburgh on Marymass Sunday but have checked and it’s definitely not there.
