Dear Nicola, If I am wrong, then so be it. It was just a guess based on (i) the fact that both tonearms were invented by and originated from persons who resided in this geographical area (Maryland, near Washington, DC) by guys who must have known each other (I believe Rabinow was deceased by the time I met Papier), and (ii) the indisputable fact that Herb Papier was a watchmaker who was very conscious of bearing quality, too, by the way. Anyway, if the correct answer is "David Shreve", I am glad the OP will be in good hands. In the 70s, I remember regarding the Rabco as an object of desire but not real craving, I think like you because it was so out of sight expensive.
At a much earlier age, the lasting image for my lifetime is that of an Alfa Romeo Giulietta Spyder Veloce pulling away from our car at a stop light, on a cool summer evening in Connecticut, and blasting off into the countryside. I was too young to drive at the time, but my destiny as a car-lover was sealed right then. I later owned a Duetto and several other Alfas and just about every Porsche 356 variant up to and including a 550 Spyder, but never have I found the right Giulietta Veloce. Oh, and I dreamed of women too, but no tonearms.
