Two pens in set, decorated with 'Silverlink Train Services' legend and logos. Stainless Steel ball point, fine tipped. Both appear to be black ink. 

See photos. Very rare and even more scarce in this as new, unused condition. 

A very scarce and unusual item, and in as new condition as it would have been when received by the train operator.  Would make a nice pen set for an enthusiast or collector.
