I have a Gold Cup Stainless like this made in 2011 and only marks on it is the Grips. The Wrap grips have the 100 year Anniversary on them. But you can tell by the Serial number it was made in 2011. They were not Roll Marked on the Gun. None of the Gold Cups were Roll Marked.I'm not so sure the GCNM or GC trophy's had the "100 year service" roll mark. I'm kind of thinking only the "lesser grade" pistols had the 100 year...
