According to this article: Pete Cooper - Notes on ENGLISH FIDDLE TUNES (Schott ED 12758), (see section The Hardy Fiddle Manuscripts) there are 2 mss - one (200+ tunes) given by James Hook to Thomas Hardy (the author)'s grandfather (also Thomas, cello) and one (97 tunes) compiled by his father (also Thomas, fiddle and viola). The article says that VWML holds copies of both.
