I wish to pass on my many thanks and gratitude for all the help and comments on my search for a replacement horn cover
Would would have thought a plastic piece of bling does arrange in price from $40 to $89.95Au, nothing but extortion and highway robbery.
Going to try a local plastic welder for a temporary fix, the of to find a replacement horn/s (Loud) and or a different cover.
Something evil looking should do it, maybe a cast self portrait

, that'll definitely stop the little feathered bastards coming anywhere near me.
Thanks again men and enjoy the holidays Marty
