Built a front wheel with the XR-19W rim

Another wheel day (and so on).

Built a front wheel with a Kinrin XR-19W rim and
a Sunour Superb Pro hub.

There's a red sticker on the rim that says X-KEYMET,
and X-Keymet is
Kinrin's in-house sales brand.

Sunour large-flange quick-release front hub, 32H
All laced CX-RAY 6x6 Italian-style
with gold aluminum nipples.

The hub shell has markings oriented in the direction of wheel rotation,
and the side where these read correctly in the forward direction
is the right side, which is my basis for the left-right orientation in Italian-style lacing.

Going back in time—here's the hub before building.
This hub has lacing marks on it, and

on both flanges,
viewed from the side closest to me, on the outside of the flange,
there are inpoke bite marks in the Yamaarashi direction.
So this hub was previously laced in reverse JIS style.
Reverse JIS lacing is theoretically justified only in one condition:
when building a rear wheel with a double-sided rear hub
for a left-drive fixed-gear track bike
with the chain on the left side.

↑This is a Superb Pro large-flange
non-hollow shaft nut-type front hub,
in other words, a track front hub, and

RIMG7754msn5a.jpg
RIMG7755msn5a.jpg
the lacing marks on both flanges
show inpoke in the Yamaarashi direction,
so it's JIS lacing.

On the right flange of this newly built Italian-style wheel,

RIMG7749msn5a.jpg
in the outpoke flange hole
there's an inpoke underhead mark, and

RIMG7748msn5a.jpg
on the left flange of Italian-style lacing,

RIMG7750msn5a.jpg
the current inpoke and the old inpoke mark align,
so it looks like
the very first time this hub was laced.

With respect to the original hub, Italian-style lacing can look like this
or be off by one flange hole,
but when I aligned the phase of the hub shell viewed through the valve hole
with Sunour's markings, this is what I got.
