I have recently come into possession of a beautiful red HS-P07 (found it in my fathers cupboard). It is technically working perfectly and in in visually great condition, but unfortunately it is missing the plastic battery door cover. The metal contact underneath that is on hinges is there but the plastic part that should fix it securely to the players metal body has gone. Same part from HS-P02MkII or HS-U07 is also 100% compatible. Could someone please help me with this part to make this truly great piece of tech complete? In the photo below I have marked the part I am missing on my AIWA HS-P07:
