Stitch, do you think this is a design element, or do you think it is a "variation" from the typical cartridge of this brand and model? Do you think any variation from any supposed norm was/is intentional, or might it be an error? Whether intended or not, it does seem like anyone might make a cartridge with any imaginable native stylus angle, when the stylus was viewed like this. However, it is harder to accept a lot of variation in the ultimate working relationship between the tracing angle and a nominal (typical) cutter angle. Did you check the angle again when the cartridge was loaded with VTF? If yes, was the resultant (VTF loaded) tracing angle then within a typical range of adjustment for a more "normal" tracing angle? Hard to say from this picture how the "tracing edges" would relate to the disc surfaces when VTF loaded.
Another thing rarely mentioned is that the front and/or rear angles of the facets of the stylus vary from one marque or model to another, not to mention the "trailing" angles (or radii), which ostensibly mimic and/or relate to the "burnishing facets" of a typical lacquer cutter stylus. All of these things must also affect the way the stylus engages the vinyl and, so, the sound.
