Thanks for the additional detail! The SDF-10 tonearm is a model from Shure, known for its high-quality design and performance. It's often used in professional audio setups and high-end turntables.
Hmm, I don't see anything like that, that matches this tonearm.. Googled Shure sdf-10. I think the copilot picked up on the Win SDF-10 logo on the front of the cartridge..
The head shell edges look like they were hand filed.
I can't find a match using Google Lens.
It may have sapphire cups installed for the pivots, one of the things done when upgrading the AR tonearm.
Really interesting!

Lol. Guess I'm on the hunt for a decent tonearm! My guess is this was one of the thorens offered by the factory without a stock tonearm.
This project will utilize all the skills I have picked up working on stereo gear. Replacing 50 year old capacitors (phase linear ), wood cabinet refinishing (AR's), and mechanical reworking (teac tape decks)... Ha.
That's the free thinking I love on this forum. I'm going to replace the tonearm, but continue to try and figure the story behind this one. Thanks for the idea.
I had a design I abandoned that used a carbon tube for the arm. It was for kite making.
Light and stiff but rang like a bell. Headshell was porous ceramic- which I like and will keep using if I ever make what ever version I’m up to now. New arm tube is completely radical sci-fi shit. Patent worthy even but those are expensive… light and stiff but should have no specific resonant frequency.
Length: the longer the arm, the lower the tracking distortion.
