Just to let all know, I sent a 28/35/50 Tri-Elmar-M, Version II, to New Jersey for a CLA and 6-bit conversion to use on my M10.
I promptly received an estimate, email updates that I could follow its progress, and received the lens back (this past week) in 2.5 months.
This is great considering the lens was sent to Germany for the service.
My previous experiences with Leica Customer Care, a CLA and eyepiece adjustment on a 135mm Elmarit-M and a sensor replacement on an M9, were just as satisfying.
They are Tops in my Book!
