Kdv Rbv N127 Boy 16yo With 10yo Hc New 12 2021 May 2026

First, the acronyms: KDV and RBV. I think KDV might stand for "Kinderdienst Verordnung" in German, but that doesn't make much sense in an English context. Maybe it's a German horse name or a specific term in another language. RBV is more familiar—possibly "Registered British Volunteer" or "Royal British Legion", but again, not sure. N127 could be a number or a model, like a car or equipment. The rest is clear: a 16-year-old boy with a 10-year-old horse (HC = Horse Care?) and new as of December 2021.
