I have a 11 degree driver that has a plain silver head very small by todays standards, on the bottom is Titleist in black letters, a red "1", and "LOFT 11" in white.  On the top it simply reads Titleist in black. There is a black plastic cap at the bottom of the shaft above the hosel that has "co6b".  The shaft is a True Temper Lite and the grip is golf pride "Grip Rite, Swing Rite".  I assume all of the items are original, I carry it in my bag and use it like a 3 wood.  Any idea of the history on this club and how old it is and should I still be hitting balls with it.  Thanks for the help.
