I have to respectfully disagree.. during my time in Kandahar in 2009/2010 I saw alot of stuff in the market with serif stamps - fake WW1-dated British surveying instruments being an espescially popular item. I think Afghan fakery has evolved alot over the last 10 years or so as they start dealing with a more and more educated consumer base.
Not that that stopped a certain young Captain from battlegroup headquarters from buying about $2000 worth of ``diamonds`` at the KAF market...
