Wanted 250 Hi-Level race megaphone
 

Trying to find a race megaphone for a high level system on a 1968 250 narrowcase race bike, or any plans to make one. The mega is 'S' shaped and runs against the outside of the top of the right hand side rear shock. No one seems to make them any more, so any info on someone who might would also be appreciated,
cheers,
Bry
