Built a front wheel with Pasenti Brevé rim and Filwood hub

Another wheel day (long story...).

A customer brought in a wheel we'd built for them previously.

The rim is a Pasenti Brevé,

and the hub is a Chris King R45
32H, fully comp Italian lacing.

There's wear on the braking surface.
Separately, they've left a brand new rim of the same model, and they want front and rear wheels built with a Filwood hub.
However, they want the new front wheel built with the new rim.

That alone wouldn't tie the original front wheel to anything, but they're asking if we can reuse the spokes if possible.
Regardless of the nipples, I was planning to reuse the spokes anyway.
According to my calculations, the spokes should be 1mm shorter.
But the original length was rounded up at the 0.1mm decimal place, and the new length was rounded down,
so the difference before rounding was 0.78mm.
I was thinking of cutting the spokes by 0.5mm, but...

On the tangent lacing, the inpoke spokes show neck-bend deformation,
and the spoke length is noticeably shorter as a result.
I decided not to cut the inpokes at all.

I transferred the Italian-laced inpokes to the new rim and hub.

Outpoke removed from the original hub.
I'll cut this one slightly and reuse it.

Wheel's built.

Filwood bolt-locking front hub (not axle nuts), 32H,
fully comp Italian lacing.
Fresh nipples throughout.

Rewinding a bit chronologically—this Filwood hub has pretty rough chamfer work on the flange holes.
The drill bit geometry lacks sharpness, looking kind of dull,
and the cone isn't accurate to the hole center either.
