I have a set of 2003 RAC Coin Forged irons I picked up recently. Very well cared for. Taylormade told me that the irons I have were forged by Endo for Taylormade. The serial number is on the 5 iron hosel.
I'm a bit curious, but the word was Miura forged these, but the actual club marketer/manufacturer admitted to the forging done by Endo.
Has anyone heard of this?
