This is a set of vintage Tommy Armour 845s "Golden Scot" irons made from Beryllium Copper (BeCu).The clubs feature a distinct bronze color characteristic of the Beryllium Copper material used in the late 1980s and early 1990s.They are classic cavity-back irons designed for improved playability compared to traditional blades of that era.This specific model, often referred to as "Golden Scot" for the copper version, is highly regarded for its soft feel at impact.
