Hogan IPT 1963 irons

Anybody have any experience with Hogan IPT irons? I have acquired a set and I am curious as to any opinions.

I have a set of PT3’s from around the same era…good sticks. I really think if they are in good shape you can’t go wrong with any of the early Hogan clubs. As they were well designed and tested by the man himself. He knew how to make a club that’s for sure
