Thank you for the most informative reply. It is confusing that they would call their early flat-nosed version “improved”. If you have a late 70s brochure then that narrows it down.
The revealing of the truth about BluzBroz is also most helpful. I had wondered how they could claim to have all those original stylii.
I recall that they also claim to be distributors for some companies like Nagtronics/IMS. Nagatron is gone as far as I can find on the web. Pickering is still in production in the UK so those are probably real, but overpriced.
Perhaps the flat-nosed version looked too much like an ADC. The long-nosed looks like an Ortofon.
My email is common info on the web because I have been slowly setting up a firstname.lastname@example.org
This is a dialup connection so if you could please inform me beforehand of a megabyte email I will know that it is not spam. I use 98 because it is easily repaired, but drivers, including broadband, are becoming extinct.
I know that this forum is not for commercial purposes. Perhaps I can give you a good deal on a stylus in return for the Acutex scans. I bought a supply of these recently and don’t know what they really are in terms of performance, or what they are worth.
They appear to have excellent quality control. Every cantilever is perfectly straight.
Thanks again, you have been a great help. Mark
