Aprilia Airbox Identification Help??

Hi everyone. I’m hoping someone can help me identify this Aprilia airbox?? It came with a box of parts included with an RS125 I’m rebuilding. I’ve done a Google search but no luck! The part numbers on the airbox are ‘DIS.103006, DIS103007 & A-1024’. Clearly not for the RS but wondering if the previous owner ‘modded’ this box to fit somehow?? Any help would be greatly appreciated.
