It had its 'lens' piece and another plastic piece apparently just floating loosely in there yet somehow held in place by the mouse's shell (when closed). Upon opening it, the pieces simply fell out and there's not really a clearly defined position for them, as far as I can tell.
I'll send some pics of the individual pieces, or provide any other info, if requested.
Thanks very much.
