So, AllEngelhard will be officially updated to flip 1st & 2nd series? Also, another thing: It appears older bars are more square in nature, while the newer ones are relatively more rectangle (longer, narrower). tozak's is more rectangle than the AllEngelhard I posted. That fact, along with the paritally vertical stamping, still needs to be logically reconciled, IMO. You know, it would just be easier if PM simply released their production records..
