Cutting the steerer would only be as a last resort, and I would take it to someone with the skills to do it right. (That ain't me.)
I obviously should be looking at a table newer than that in Sutherland's 3rd ed (like
JohnDThompson's table). Mine only shows Campagnolo Record Strada (39.1) and Record Pista (33.7). This must predate the arrival of Super Record. As for those C-Record era Campy headsets, maybe it's just me, but I've always found them unattractive. I had one on my Redcay and was glad to replace it with an early Chris King.

I'll see how close I can get with the NR headset I have. Maybe the Wheels Mfg option
Doug Fattic mentioned or the rather blingy example
merziac showed will be necessary. More tomorrow.
I appreciate the responses. The intent of my post was mostly to demonstrate why I'm not a hot sh*t bike mechanic. I often forget the most basic stuff. Fortunately for the world of cyclists out there I basically only ever work on my own bikes.
