Head has the mold. But also the rights to produce and sale? Who knows? May be Uli Kühnel still have them who managed the whole project in 1996 with his company at that time. I remeber that a friend told me that there was an agreement that Head can not use this mold for selling rackets on their own. Still alive?
Yeah, all of that might make it a very tough call...
Still, it would be a shame not to turn this into the type of the custom venture, in the time of Angell custom rackets, and similar offers from, Heysil, Dahcor and Zus (from Italy).
Making a frame from Boris Becker Puma mould at Head, with adjustable, custom balance and weight options, would be quite something.
And there are other room for variations, such as making the larger head size frame for those who would like it, since I still remember Kneissl Pro Stick (grey color) which was about 102 sq. in. or similar (oversize then) used by a teaching pro who was visiting our club. To him, none of the (then modern, now vintage) rackets compared to his sticks.
