Replicant 100 stylus

My ''general statement'' that styli are produced by either Ogura or Namiki

may need correction.

Some friends of my ''discovered'' that Replicant (Ortofon), Decca and

''Expert stylus'' are the same. As is/was the case with Gyger and

Van den Hul. Van den Hul designed Gyeger I, II and S (?) but

Gyger produced them. This was obviously kept secret for commercial

reasons.

My assertion is that Expert stylus (Paratrace) provide them to the

other mentioned.

Is anybody capable to check this information?
