I asked Daniel (Dertonarm) about the 'geometry' of all those FR-7 versions. He still swears by those 'antiquity' while his answer surprised me very much. The stylus in
those huge headshells is not at the same distance by all of them. So, probable, even Dertonarm was/is not able to get the right geometry for his 66/ 7 (x) combos? If I was an Aussie I would inform by Daniel about my own specimen. But the most curious thing is that my FR-7 stylus follows exactly the curve on my Mint protractor made for my FR64
with 231,5 mm P2S distance.
