well since a ruby lens hasnt been made for the Pit Boss, it would have to be custom, so if this 'Ruby Iridium Polarized" actually does exist, it would have been cut from anotehr lens and may explain the etching not lining up.. but im dubious about the authenticity of a polarized ruby lens..
If a ruby polarized pit boss exists it would come out of Oakley itself rather being cut from another lens by a customiser. If this is the case then there is no reason why the engraving would be different than what is on the other pit bosses since the engraving machine would be using the same settings.
