Or the artist of the fake knew of the Pray Manuscript and incorporated these signs into his forgery

Stephen E. Jones gets around to answering an old comment from last year:

And thanks for your tacit admission that the Pray Manuscript and Shroud of Turin share a number of common features that can only be reasonably explained by either the Shroud having being copied from the Pray Manuscript or the Pray Manuscript having been copied from the Shroud. If the latter, because the Pray Manuscript has a confirmed existence since at least 1192-95, the 1988 radiocarbon dating of the Shroud to AD 1260-1390 has to be wrong.

For the Pray Manuscript having been copied from the Shroud . . .

Good analysis at The Shroud of Turin: `Or the artist of the fake shroud knew of the Pray Manuscript and incorporated these signs into his forgery?’
