Putterho I hope he has it in hand, as he agreed to meet me tomorow 🙂 I've also asked him a bit more about the putter, because he listed it as an "american classic", which I thought was the bullseye with the copper weights. He said that he got the putter from Peter Robert Mitchell, who, according to my research, played on the European Tour in the 90s/00s.
Honestly, either this is a very elaborate troll and I'll waste a few hours or the guy doesn't really know what he is selling, which I think/hope is more plausible, given that golf is still very much a niche sport in Switzerland and gear knowledge is pretty much non-existent. But I will know more tomorrow and will update the thread in any case 🙂
