This "Hand-Made" Part must be the most Fabulous Part on the WarBoy :
What you see is NOT an Oil-Bath 1942 Air-Filter .
Steel-Built just like a "Mirror Image" ( see the intake on the WRONG side ! )
This "FAKE Air Filter" is in réality the WarBoy's BATTERY COVER .
It also contains the C.D.I Elecronic Ignition Box .
