I just purchased a set of Titleist Tour Model irons and have a few questions about them. The number etched on the feral is 16652 and a small 7 is etched on the hozel near the feral. What do those numbers mean? The irons have Titleist Tour Flex steel shafts, what is the flex for Tour Flex? Any idea as the the year/years produced? The heads haveTitleist on the sole and Tour Model on the back on the head closer to the toe than the heel. They do not say forged on them but I assume they are??
Thanks for any information you have. Bill Beurmann
