Can anyone tell me anything about this Ping putter? I picked it up today with the plan of cleaning it up and playing it but figured I would just double check that it wasnt worth anything first.

The inscription reads:

U.S. PAT. NO. D207227
KARSTEN MFG.CORP.
PHOENIX, ARIZ. 85029
MADE IN U.S.A.

It has a slot in the bottom and no alignment marks if that matters.

I’m looking for cleaning and conditioning product recommendations that are good for my new white leather shoes. They are golf shoes so they will be getting pretty dirty on occasion and ideally they would remain waterproof. I have some redwing waterproof leather cleaner and some leather cream with neats foot oil that I use on my work boots but I’m not sure if they would be ok or if there is anything better out there.
