I've recently bought some Cuban cigars from a very reputable cigar shop.

I'm not concerned at all about their authenticity, but out of interest I would like to know which factory they come from. Useful info for future purchases.

Is anyone aware of a resource listing the codes and corresponding factories?

If anyone is interested the codes are as follows:

Cohiba Robustos
Boxcode : PFY MAY05

Punch Royal Seleccion No.12 Cabinet of 25
Boxcode : SUH SEP01

Partagas Lusitanias Cabinet of 50
Boxcode : BYL ABR05

Cheers,
Scott.
