imageIn response to this very important quotation of Dr. John Tyrer provided by Maria da Glória Gonçalves Barroso of the Centro Português de Sindonologia:

There is therefore some doubt as to wheter the sample described by Professor Raes as Piece II is the edging strip or part of a patch.IT IS IMPORTANT THAT THIS MATTER BE RESOLVED IF IT IS INTENDED THAT THE FORTHCOMING CARBONDATING TESTS ARE TO BE MADE ON RAES SAMPLE.THE PATCH IS PROBABLY MEDIEVAL. (Caps not mine)
