I've heard that juice harp derivation as well. I thought it was due to the fact that drool can often accompany the struggle to wrench sounds out of the little bugger.

I even have what may be an rare example of one of these with what appears to be a brass body. Unfortunately the reed has become dislodged from the frame and I don't know how to properly reattach it. Are there any repair gurus who can supply hints as to it's repair? I'm afraid I won't find anything if I search the yellow pages. It looks as though the metal in the frame is just smashed down onto the reed to hold it in place. I don't want to wreck it by attempting to do this the wrong way.

Thanks, reg
