My buddy (the yo-yo impresario Doctor Popular) posted this mystery object on his blog.
From the page: The mystery object is made out of brass and belonged to Rachel's grandmother. It has an arm with three joints and a collapsible tripod stand. When fully collapsed it makes a flat 3" x 4" square.
As mentioned before this is an heirloom piece, but Rachel has never been able to figure out what it was originally intended for, as a matter of fact I'm only making the assumption that the three pieces on the bottom are even intended as a stand. For all I know the pointed end could plug into something.
