The cartridge design comes from Decca's original mono cartridge. This enplanes why the vertical coil assembly sits right on top; at a 90° angel to the lateral (mono) coil, instead of the traditional 45°/45° configuration of nearly all stereo cartridges. The line drawing in the other post is very correct, but let me add a few words of explanation.
There is no cantilever in the sense we think of one, surely not one that could simple be replaced when replacing the stylus. The stylus fits into the tip of an L-shaped tempered steel blade that protrudes down through a cartridge body. The other end of the L is clamped tightly within the body. A tiny tie-back cord affixed to the vertical part of this L-shaped piece(which for lack of a better word sometimes is called a cantilever, but it does not meet any definition I know of as a cantilever in audio or other places) just above the stylus and is literally tied back and attached to the same set of clamping plates holding the other end of the L-shaped blade. This creates a kind of spring like suspension. The stylus end of the L passes through a coil-and-pole-piece assembly that tracks the lateral motion, while another coil and magnet at 90° to the lateral one registers the L piece's vertical movement.
