unique tonearm Brooklyn Bridge

I know which one you are talking about. It looked like the arm of a crane - triangular form when viewed from head-on with side braces between the three main lengthwise elements (side braces also formed triangles with the lengthwise elements forming the third side of the triangle.

I remember red highlights for some reason, and a north European origin.

I remember seeing this at the same time as a Scheu tonearm, and for some reason I think it may have been the original or prototype version of the Scheu Cantus, but I am not sure. I'll have another think...

Alternatively, there was once a Norwegian tonearm (WKarlson?) which looked like it would have a lot of rigidity but a HUGE amount of horizontal mass, but that was made of metal, not wood.

There may be no relation to Scheu. I just remember seeing them at the same time, and note the acrylic Cantus has that same shape. I was probably associating things which had no association other than their proximity in my memory.

There was a tonearm designed by Randolph Hedgebeth, an architect, and it was called the Golden Gate. It was made of wood, in a truss or spaceframe structure. This may be what we are thinking of. But I remember (or don't as the case may be) something a little bit better made than the picture I could find on the web.

Google is your friend. :^)

Well Lew... someone is a fan of the L-07D arm...

Lew,
The photos (which may be being blocked by a popup blocker (I can see them still, on an iPad tethered to an iPhone in the back of a cab in Tokyo - I LOVE cool technology like this) show the Aura TT with three arm pods, one holding the black balsa creation of Mr. Whittaker and the other two holding L-07J tonearms. My comment was just in relation to a comment you made on the arm in one thread (something about how it didn't have many fans as I recall). I agree with you on all points on the tonearm (though I tend to think of it as pleasing coloration rather than absolute lack of it). Cheers!
