Excellent used condition Honda CHF50 Metropolitan scooter luggage box / helmet compartment.  For model years 2002 2003 2004 2005 2006 2007 2008 2009.  See photos for condition.  There's a small notch cut in the bottom of the battery cover with a Dremel to allow for a battery tender cable to pass through.  The Ziploc bag has mounting hardware in it.

These parts come from a 2004 model with a legitimate 2681 miles.  It's a Southern California bike, always stored indoors.  The last few photos are of the complete bike.
