COWL INDUCTION THROTTLE ARM

[ALLZS]

HOW CAN YOU TELL IF A COWL THROTTLE ARM IS ORIGINAL OR A REPRODUCTION ? THANKS

Two things I've noticed - repros sometimes have the clamp bolt head welded to the arm, most all of them are painted, My original Z11 arm carries a separate bolt, plus it appears to be either phosphated or plated, definitely not paint. Hopefully we'll have some other owners chime in -
