Hey Peter
Be careful over there in Turkey.
I am not going to be the one to be able to offer major help on this however, a couple questions come to mind. From my limited experience it seems the provenance, and the story of how things were acquired, can be quite important. I have a feeling without any hard provenance (written or physical) it's going to be impossible to be sure. Do they have his name on them by chance? IS there a story around how this person acquired them? Obviously the first thing that can be verified is that the cleats are period to when the seller says they are. We all know about the recent Ruth signature fiasco. It makes authentication (or not) easy when it's not even possible. Like if the cleats were only made after he passed away, unless we really want to get grim, he couldn't have worn them
