WTT: Spec Trispoke front for deep front

I've got a Specialized Trispoke, pre Hed H3. Front, clincher, 700c.
Condition is good, there's a touch of corrosion on the axle, but it's pretty
close to perfectly straight and round. It's been my primary TT front wheel
this year.

I'm looking to trade it (straight up or with cash one way or the other) for
a deep section, 700c clincher front. Examples would be Zipp 404 or 808, Hed
Jet 60 or the Real Designs version of that, a Cosmic Carbone...something
50mm deep, clincher.
