I'm not sure but probably is never let go.
its not a font that i know of. the graphic was manipulated from the original logo by "titleist" http://www.titleist.com/images/shell/logo.jpg
I just created a logo with a font i made based off of illest heres a link look at it http://tinypic.com/r/1es9if/5
This one is similar but i'm looking for that as well
I would have to say that the most likely option to achieve 100% accuracy of this logo is to modify it using the Titleist Golf logo as a source.
Nobody has been able to pin-point this font yet: https://www.myfonts.com/WhatTheFont/forum/?q=titleist
