I see what you mean by the cobra profile. I checked all my Stereohedron styli (which aren’t that many) and compared them to the ellipticals for the Stantons and Pickerings and they are consistent with your descriptions. None of the ellipticals have the cobra profile and it does appear that the Stereohedrons are mounted on the flat “spatula” surface and is bent so that the stylus is parallel to the record surface. At least the cobra profile is a good first step in determining whether or not it’s a Stereohedron.
There is no mention of a special high polish. I believe the intro was just lifted from an old version that talks about features that no longer applies.
I also have a sheet from a N.Y. Stereohedron II 681 cartridge. There is no Instruction Manual, but it does have the blue calibration card and a info sheet with the Stylus Type and Dimensions specification: "Stereohedron II, Scanning radii: .0002 - (scanning); Contact radii: .0030 (Contact). Stylus Color: Black with EEE-II-S.
I don't have any other D81-IIs styli to compare but I do have a product sheet from Stanton that states the Stereohedron II 881s stylus is designated as "D81IIs" The Hollywood stylus is designated as "II-D81S" but that could be because there wasn't enough room on the stylus grip.
Let me send some overhead shots of the same styli
Here's the Hollywood 881s

The 681 is definitely not flared, but I'm not sure about the 881S. What do you think?
I know I have a Pickering XSV3000 and an old New York 881S. I'll get shots of their styli.
The Instruction Manual for the Hollywood 881 Mk IIs says "881 Mk IIs with Stereohedron II Stylus". The intro talks about the 881 being the "Professional Calibration Standard", and "individual Calibration test results are packed with your unit." but there is no blue calibration card that normally comes with the cartridge. "The new 881 MkIIs uses a new Stereohedron II diamond shape to give improved groove tracing while reducing groove wear." but the Specification List has the tip dimensions for an elliptical stylus.Does it say elliptical special high polish? Any chance you could take a photo of those specs? I'm wondering if it could possibly be a typo. I guess the best thing to do would be to have someone scope it. @marcmorin
Also, could you compare it to another D81-IIS to see if there's anything different about it that might be used as a way to differentiate it from a Stereohedron version?
