You don't hear people asking "how much for that Mona Lisa painting 
     mate ?". I think , judging by the prices people will pay in the UK 
     that the stuff you've got is worth "a bit" more that a tune up or 
     junked carb.
     
     I know a guy who imports stuff to England, you might want to give him
     a call,
     
     His name is Jon Abbot and his phone is +44 21 554 7963.
