Subject: SU carb needle markings.
i have 2 SU carb needles marked eother "RG" or "BG" wich are very "trick" 
looking .
i'm suspicious that if they are not a competition needle from BMC that they 
might be from robert (bob) griffith of BHP development.     does anyone still 
posess the needle charts i remember seeing somewhere in the shady past of 
rather long ago to possibly verify this?
chuck.
considering a richer running bugeye....
