From W. Crum's catalogue of the Coptic mss at John Rylands library in Manchester I attach the description of several mss (see nos 25-29; Plate 2 gives a photo of 28) in Greek using some unusual notation consisting of varying number of "oxeias". The entire book can be downloaded from here. It is quite remarkable that the first hymn is the well-known theotokion "Epi soi chairei".
