Just to let everyone know I have spoken to a fellow pinsider who is a British expat now living in Czech Rebublic and he has kindly offered to authenticate the game/seller for me.
He has contacted the seller but they have not made a time/date to meet up yet.
I too am interested in the pin but being based in Northern France makes things a bit easier for me with regards to shipping.
Whatever his findings are I will pass them on as that's only fair.
