Hmmm,
I may well be mistaken on this - but wasn't there also a 2mm aluminum keyed lockwasher that came with some early super record headsets? I seem to have one on my 74 or so Raleigh Team bike - and if memory serves me (which it doesn't always), I've seen SR headsets in the box with a thin aluminum keyed lockwasher as well. In fact, I don't recall seeing a steel lockwasher on any early SR headsets.

\r?\n> The Super Record headset originally came with a chrome steel keyed
\r?\n> washer that is 2mm thick. Later this was changed to a aluminum keyed
\r?\n> washer with flanges and lettering around it that is 4mm thick.
\r?\n>
\r?\n> As Tom mentioned, there is a Campagnolo tool that clips between the
\r?\n> wrench flats on the adjustable cup and lock nut to keep the two
\r?\n> headset wrenches from slipping when you adjust the SR headset with
\r?\n> the early steel keyed washer. Tullio eliminated the need for the
\r?\n> special tool by going to the lighter aluminum keyed washer with the
\r?\n> flanges that also kept the two headset wrenches from slipping.
\r?\n> Lighter and a more sophisticated solution, right?
\r?\n>
\r?\n> Ahhhh, now the conundrum... is the 4mm keyed washer in aluminum
\r?\n> lighter than the 2mm keyed washer in steel. Well the answer would be
\r?\n> yes. But what about when you factor in that the steerer tube is 2mm
\r?\n> longer when using the 4mm aluminum keyed washer rather than the 2mm
\r?\n> steel keyed washer? Which is lighter now?
\r?\n>
\r?\n> Anyone?
