A quick online search reveals that this C.G.Aspiotis is a Greek publisher from Corfu [1] who founded a successful printing company (lithography) that survived until 1928 (when it merged with another entity). Now how might he have come to own this book? It turns out C.G.Aspiotis was the son of a N.Aspiotis [2] who was born in 1816 and died 1891 (thus years before the son sold the book to the British Library). How could the father Aspiotis get into possessing such a treasure? (Assuming he indeed bequeathed it to his son?). It turns out N.Aspiotis was an important iconographer [3] (painter of religious icons in the Byzantine culture). Again a search reveals that circa 1860 [4] he traveled to Montenegro on commission to paint a church. Which one? Here the trail becomes hazy if one only uses a web browser. There are quite a few Orthodox monasteries in Montenegro. Even a casual scan reveals that several of these go back to the 14th century. [5], [6]. One could visit them and ask about records of the N.Aspiotis commission etc. So there you have it, a plausible trajectory: from Theodosius of Prinkipos living in the 13th century in the Constantinopolis area the book - of obvious religious significance to the Byzantines - was smuggled to the Montenegro area ahead of the advancing Ottoman invasion (which ended in 1453). The book remained in a monastery library for centuries. It was given to N.Aspiotis, possibly as payment for his painting work. Assuming the record of such a transaction can be found the likelihood that the book was faked feels negligible.
