"H-B" Studbook, Vol. VII 1968 - A Register of the Pedigrees and Performances of the best-known Racehorses, competing under both Jockey Club and National Hunt Rules, which are ineligible for entry in the General Stud Book F. M. Prior, forest green cloth bound with gilt titles, near fine, 182 pgs., nine b/w photographic plates. Many good racehorses, including Flat and National Hunt winners, were debarred from entry into the General Stud Book as a consequence of the "Jersey Act", which stated that no horse or mare could be considered eligible unless "it can be traced without flaw on both sire's and dam's side of it's pedigree to horses and mares themselves already accepted" in earlier volumes of the Studbook. The "H-B" Studbook volumes were Miss Prior's endeavor to preserve the pedigrees and histories of unrecorded winners and their families.
