Dont take this the wrong way but, i am confident you are going to have a hard time getting interest on this site based on the fresh account and no trade cred. doubtful you find anyone willing to take such a risk on 15 year old cubans of unknown origin, storage, from an unknown poster.
I would highly recommend building up some cred with some smaller trades, maybe one of the PIB threads or something and then you MIGHT see some interested in the Cubans. Either way, i do wish you good luck and hope you can find a trade you re good with.
