How to search for J-bend spokes?

[dsillito]

Hi all,

I'm considering re-building a long-used (at least 25 y.o.) Corima aero tubular rear wheel (minor cracking starting around the valve hole), and am having a tough time searching for the correct spokes, in a preliminary search. The drive-side ones are bladed, J-bend spokes, but the orientation of the spoke head is turned at a right angle to the standard. Instead of the flat circle of the spoke head facing the flat part of the spoke, it faces the edge.

In searching for that kind of spoke, when I add terms like "spoke head orientation", "turned 90 degrees" etc, I just get swamped with articles about the orientation of spoke heads either inside or outside the hub flange, or standard bladed spokes that have turned sideways and need to be straightened (Incidentally, why does the internet need hundreds of articles explaining this, and how to straighten them? Is nobody in charge of a periodic cleanup/purge of the electronic dump we call the internet? )

Any tips on what these spokes are officially called, or where to source them? I suppose I may just have to go with a round cross-section if it is too much hassle. Something tells me that twisting a standard spoke that far wouldn't be good for the strength at the elbow. I haven't committed to getting a new rim and re-building. I may just tuck the hub and spokes into the overflow drawer, to be cleared out by whoever inherits that terrible job after I die.

I've included photos of the drive, and non-drive sides, in case my description was inadequate.

Thanks in advance
