Most of the newer AP2 models would have the year model on the hozel. ie, 718.....Titleist started making the AP2s In 2008 and continued thru 2018, on a two year cycle. If you look below under previous models you might be able to find the model. Your set has been registered with Titleist and states it is a set of irons, AP2 with the serial number you provided. When you asked for model, I assume you meant year. A picture might have been helpful. It might be a 2008, 2010, or 2012.
