Built a front wheel with a mystery carbon hookless rim

Another wheel day (and so on).

Built a disc brake front wheel with a carbon rim
whose origin the customer requested I keep under wraps.

46mm tall (← looks like it could identify it from this) hookless rim,
and the weight for a rim of that height is remarkably light, but

part of that comes from omitting the decorative carbon layer
on the outermost surface of the rim sides.
In the photo above, there are spots where the carbon surface
appears to have shrinkage,
but when you actually touch it, you don't feel any dents.

I have two 24H rims on hand for front and rear wheels,
and on the label with the serial number
embedded in the outer edge of the rim,
it lists a nominal weight of "370g".
Both rims came in lighter than that in actual measurement,
but if you added another layer of decorative carbon,
it would probably come out to the nominal weight.
