The last time I reshafted my mid-80’s MacGregor Muirfield irons was in the late 80’s or early 90’s if I recall.
I purchased a True Temper .355 iron set from Maltby with copy that indicated something like “a special iron shaft designed for hard hitting players”.
There was a TT part number but I have forgotten what it was. Something relatively routine such as DBIS, etc.
I’d like to obtain more of these shafts as they remain outstanding in terms of playing characteristics.
Does anyone have access to catalogs from this period that can help?
Thanks in advance.
