Anyone know what arm that is?

Seems similar to SME setup, but I don't see any anti-skate.

Any help will be appreciated, thanks, Elliott

btw, TT71. Any real reason to avoid TT71 or avoid TT61? I have TT81 downstairs. Are they all the same cutout, IOW, any plinth with cutout for any of them will fit any other?
