Help Identifying MacGregor Jack Nicklaus "Grand Cypress" Model Iron Set

[MM29]

I am looking to replace a missing iron in my vintage set. They are identified as Macgregor Jack Nicklaus " Grand Cypress" irons. I am not finding any results using google or ebay and was wondering if this is a standard model produced by MacGregor that was stamped for the course. If that is the case I would be happy to obtain the missing iron of the same model without the stamping. Anyone that can lend some knowledge on these, it would be greatly appreciated.

Looks like a MUIRFIELD forging to me.

I was thinking the exact same thing - Muirfield.

Thank you for the insight. I was leaning that way, but trying to figure out which version/year. Noticed most Muirfield heads have "TOUR FORGED" on the hosel. Comparing the muscleback portion and counting grooves in the meantime.

Pro-81 or Pro-86 forging.

Is that a custom stamp??, never heard of that one before, not pro shop or sporting goods store.

I'm going to guess: a set of Muirfield irons purchased at the pro shop at the Grand Cypress GC ( a Nicklaus designed course) , hence the stamp.

 

You might want to find out the year when the Grand Cypress GC opened for play and compare it to the model year of the irons.

Thank you for the helpful info. I also emailed MacGregor UK in hopes they may have some history to share.

Grand Cypress opened its first course in 1984, in 1988 Jack built "the New course" his tribute to Saint Andrews

That's in the sweet spot of the Muirfield Irons release, isn't it? They look pretty much identical to my Muirfields, although the toe muscle looks slightly more rounded. That could just be a trick of the light, though.
