Yep had them in the shop I worked in 1992 when Faldo won the British Open that summer. Irons to match, they were slightly more expensive than a set of TP 18s / TP 19s at the time.
There was also a set of manganese bronze irons mizuno quad PC I think too which had the tops of the toes cut off, equally different looking. In those days it was just wilson, mizuno, ping, taylormade, Dunlop maxfli, top flite irons and woods (thunder heat driver) , ram tour grind and yyonex were very popular and cobra was a top
line. Callaway hadn't really come out with anything then and titliest only had the tour model, tornado and DTR irons the DCIs I don't think had come out then. Those were thedays!! Zero forgiveness forged blades, great fun!!
