I do not believe this is C. Valentine (loddigesii x warneri), but rather C. Dinard 'Blue Heaven' https://op.aos.org/AwardProfile/Summary/50350.
Aside from striking similarities, F1 hybrids of C. loddigesii generally have lips with diluted color, unlike this clone. Also, all segments tend to strongly favour the C. loddigesii parent. Even some of the better hybrids [i.e., C. Beaumesnil 'Parme', and 'Juan José' FCC/AOS (https://op.aos.org/AwardProfile/Summary/90874), or Rlc. Mem. Victoria Kam 'Fascination' AM/AOS (https://op.aos.org/AwardProfile/Summary/117165)], you clearly see C. lodigesii influences, but there is almost none in C. Valentine 'Barry Paul Mezey' AM/AOS.
