I believe that was the original lofts. I know the PW was 50 degrees and there were 4 degrees difference. What I'm not 100 percent certain of was whether they went to 3 degrees from the 5 on down or the 3. I've head a set since 1992 and after having them regrooved and replated I still play them. Greatest irons ever. Hope this helps.
MacGregor registration number A060?
1987
Go to the Ping website and check past clubs. They will most likely be the same lofts as the current i range.
It varies with the brand or model of the club, but it is usually about 17 degrees.
On clubs such as the Driver, fairway woods rescue clubs and wedges usually have their lofts on them. For irons you can get a list usually from the manufacturers website.

Muirfield Seamount was created in 1973.
Jack Nicklaus both designed and played the 1967 VIP irons from 1966 to 1976 when he then switched to the investment cast version of the club that he played until 1980. The original prototypes did not have the crowns on the faces and he played with them in 1966 and ultimately settled on the production model design with crowns on the faces in 1967. The 1967 model had a bronze ferrule that was unique that was later changed to a black ferrule in 1968 along with a smaller font "by Nicklaus" on the back toe of the clubhead. Jack was under pressure form MacGregor to promoted the investment cast technology of the 1970's which reduced manufacturing cost and he collaborated with David Graham to design the Jack Nicklaus VIP cast irons and both he and David Graham played that model as MacGregor staff members. In 1980 David Graham designed a prototype iron for Jack Nicklaus that he went on to win the 1980 US Open and PGA Championship with and was the design then incorporated in the Muirfield irons in 1983.
