Hi Lew, In the German magazine ''LP'' the whole story about Gyger can be
found. They never made profit from their styli production. Probably because
Van den Hul who designed Gyger I, II and S (?) stipulates his right to sell
them under his own name. So Van den Hul sold many more than Gyger.
Gyger is out of styli business. So Benz uses at present ''micro ridge''
which is produced by Namiki. I am not sure but Ogura seems to
produce elliptical styli only. Than we have the curious ''lack of boron''
for the boron cantilevers. The fact that sapphire is more cheap may
explain the situation. I hope J. Carr will help with , say, the truth value?
