Built a wheel with Campagnolo Omega 19 WO rim

Another wheel day (and so on).

A customer left me a wheel built with a Campagnolo Omega 19
WO rim for servicing.
The size is 650C.

All spokes front and rear are CN brand 14-gauge plain black,
with gold aluminum nipples. The front wheel is inpoke radial laced.
Both wheels have a slight centering offset,
and the radial runout could use some tightening too, but there's
no lateral runout at all.
Plus, the spokes are thick and the rim internal diameter is small
(= shorter spokes), so it's turned out to be a fairly stiff wheel.
But the customer wanted a rebuild, so

DSC00453amx12.jpg
I rebuilt it.

Evo hub 28H, black full Comp laced with black aluminum nipples.

Looking at Campagnolo rims from this era, from the same side

DSC00467amx12.jpg
the orientation of the Campagnolo sticker text and

DSC00468amx12.jpg
the rim model name sticker on the opposite side
are oriented in reverse.

So, place the Campagnolo side on the ground
oriented so you can read it the right way up, and look up from there

and the model name side also reads the right way up.
If you go with this same orientation and

DSC00471amx12.jpg
place the model name side on the ground, the text orientation becomes upside down, and

DSC00472amx12.jpg
looking up at the Campagnolo sticker from there,
that's also upside down.
There might be different interpretations of which way is "correct,"
but I assemble them so that "when viewing the wheel from the right side with
the Campagnolo side on the ground, the text reads the right way up."
The front wheel was like that before the rebuild too, but

the rear wheel was the opposite. Regardless of which is "correct,"
I think the front and rear should match.

The rear wheel before the rebuild was
DSC00457amx12.jpg
an Evo hub 28H full Comp lace.
If I kept the freewheel-side spokes as-is and
changed the non-freewheel side to a CX-RAY 6-cross pattern,
that would be equivalent to half Champion lacing,
but that's just a spoke weight ratio issue, and
I don't trust CN spokes the way I do DT or Sapim,
so I don't reuse them.
Since I'm doing half Comp this time anyway, 14-gauge plain
won't be used.

Built.

Black half Comp 26-lace with black aluminum nipples.
I'll do the truing later.
