I think they are Torrington or less likely Robergel thread. Were the original spokes galvanized? Torringtons were great spokes other than the galvanized dullness and I suspect Harlan may have liked their strength and thinness in the middle section.

Well, in my continuing Hi-E Project, having destroyed one rim trying to true a Hi-E wheel with old corroded spokes, I decided to respoke, but hoped to reuse the special Hi-E nipples. The original spokes measure 15 ga on the end, so I ordered some 15 ga DTs to rebuild with. But when they arrived today, I found I cannot thread the Hi-E nipples more than a couple of turns onto the DT 15 ga spokes. Did Hi-E make their own spokes as well as nipples? Did they use a non-standard thread?
