Is this a box in your possesion, or an advertised code? It appears to be inaccurate in the form you posted, but if this is from a trusted vendor's website, I'd guess that the "9" is actually an upside down "G", which would indicate the Partagas factory. Also, the "C" in the date could have been the result of some sort of dyslexic typo, and is really an "S" on the the box. FPG ONSU would certainly make sense. Do you mind posting the brand and name of the cigars?
