I would guess Rapido would know. Have you checked with them? They have email and are on Facebook too. Bill Schneider might see this and reply too.

It is a hand-finished pre-production sample, and depending on how early in the process is probably from 3D-printed masters. But it is worth telling them sooner rather than later, because if it's not altered in the CAD prior to cutting tooling, then it's much more expensive to fix.
