Symbaloo/Google search reveals that almost all references to Pylos tablet Py TA 641-1952 (Ventris) are attributed to Richard Vallance Janke:

Since Richard is now in the process of deciphering at least some of the vocabulary of Minoan Linear A in his Glossary of 134 terms in Linear A, it is quite possible that someday he may be ranked alongside Michael Ventris.

especially in light of the fact that his article, Linear B tablet Pylos Py TA 641-1952 is the “Rosetta Stone” for Minoan Linear A tablet HT 31 (Haghia Triada) Pottery and Vessels, is to be published in the prestigious international annual Archaeology and Science, Vol. 12 (2016) Belgrade ISSN 1452-7448,

It is critical to note that Richard does not claim to have deciphered Minoan Linear A. Such a claim would be preposterous. What he does rejoin is that he has been able to successfully decipher around 130 Minoan Linear A terms more or less accurately.
