I wonder if such applies to the always esoteric French brands like Simplex Huret and Vitus. As typically, the French always want to throw everyone a curve by having a different thread pitch or something...... just to be different? Heck,! Simplex don't even use springs on their dropout adjusters, but tiny black pucks made of Delrin (of course) to keep the adjusters from backing out.....
