I think I explained myself as why anyone should have them AND I posted pictures. Yes you should keep yours in the box. With very few exceptions, models loose their value if without box. And until someone (like Exoto was supposed to) comes out with a model of the 330P their (Joueff) value will continue to rise. I know it is not in the picture but I also have one just like yours-plain.
I use them as a basis to build the whole existing 1:1 collection. So, thats 0844, 0846, 0848, 0850, 0854, 0856, 0858, 0860 and David Piper replica 0900. Just have a look at my thread: http://www.ferrarichat.com/forum/showthread.php?t=139128 Regards, Wouter Bekker
