What is this ARM?

Looks like an ADC, I could be wrong.

Try "Sumiko". Beautiful turnable BTW.

it looks like an oracle prelude.

Pbb

Wow - that's a vintage audiophile memory.

If my fuzzy memory is correct, the ADC tonearm had a dome shaped counterweight, and did not have the little outrigger thingy that I notice in the photo.

Also, it was not quite in the same big league as the Oracle turntable which would make it a peculiar match.

If I were betting in Vegas, I might also go with an Oracle arm, but only because I dont recognize it and I otherwise know nothing about them.

Yes, a gorgeous turntable, a real classic.

The glass base it sits on says, “Premier Oracle Reference BRAS Pierre Lurne”. “Bras” is French for “arm”, so is it a “Pierre Lurne” tonearm?

I think Lloydc is right. Here is a link to info about the Pierre Lurne arm, including a link to an owner's manual (in French!):

Did you use image enhancement to read that?

A little quick Googling for Pierre Lurne revealed that he designed the linear tracking arm for the Goldmund, and that this particular model is the Audioeca/Pierre Lurne Arm 2, illustrated and briefly described here:

There's some good news and bad news: You can download the tonearm manual from that website, but it's in French.

looks a little like the Magnepan Unitrac.

Cwlondon, I am dating myself, no?. I had my doubts.

The proper answer certainly appears to be that from Jb53.

Softmachine, if you have problems with the French, let me know and I will interpret those portions that give you trouble. It would appear that you can garner a lot of useful info solely from the schematics provided in the instructions.
