Wanted: WANTED - Redfield Battlezone 6-18x44AO 5.56NATO or MOA Elevation Turret Knob(s)

Just a shot in the dark (but we know how well THAT worked out for Oscar Pistorius !! hahaha), 

I had a relative give me a sweet old Redfield Battlezone 6-18 x44 AO scope that he had setup on a .308, so he had the corresponding elevation ballistically calibrated turret knob on the scope, but sadly, he somehow lost or misplaced the other turret knobs that came with it ! One of the knobs that they supposedly came with was one that was NOT a ballistically calibrated, so it would have 1/4 MOA markings instead of yardage. This is ideally the one I'd be after, but the ballistically calibrated yardage knob for 55gr 5.56NATO would also be perfect since this is destined to go on my wife's Ruger American in 5.56. I know I can get ballistic tapes from a variety of sources, but I will do those as a last resort if I can't come up with either knob(s) ! I'd just rather have the rest of the goodies the scope came with ! I'm just weird that way ! 

Please 'shoot' me a message if ya have either or both kicking around and don't mind parting with them ! Let's talk turkey ! Thanks all !!
