Rega RB2000 - Bearing Play

Bought an RP10 (used, but from a dealer).  The arm has substantial side-to-side bearing play (a good 1/8" in either direction) and a bit of up-down play we well.  I've used & had numerous Rega arms and have never seen this before.  I found some threads elsewhere suggesting this is a manufacturing defect.  (Since these arms are hand-made, how would this escape QA?)

Anyone have any experience with such an issue, and getting it resolved?
