I have 2 JC Whitney style trunks.  They are basicly a GIVI copy.  1 is a gloss black medium the other is a large flat black.  Both are brand new in the box.  $45 for the medium or $55.  Package deal  $90 for both.  Prices are plus shipping from 61701.

Got any pics of the large and how many liters it holds?  I have a 39 liter JC Whitney/Ebay special and I think it is considered a large but I have read other places where that is considered the medium.

The large  one is  22 1/2 wide 16 1/2 deep  11" tall.  liters measurment 40
  medium is 18 1/2" W  16" d  11 1/2" t  33 liter.
