"The Ezeldeen Taha Eldarir Collection": Charles Ede and the Master of Secrets (July 2016) [UPDATED]

One of the earlier pieces from the Ezeldeen Taha Eldarir collection to come on the market was this piece being sold by Charles Ede:

Old Kingdom, 4th-6th Dynasty, c.2613-2181 BC
Limestone

ENQUIRE

Enquire indeed, do they have any documents for the above?  The item is also described here in a little more detail:

Egyptian hieroglyphic relief fragment Old Kingdom, 4th-6th Dynasty, c.2613-2181 BC
Limestone Height 23cm, width 38cm.
The crisply carved hieroglyphs in raised relief read ‘Master of Secrets’. Dividing lines below and above, partial hieroglyphs in the lower register seemingly include a bread bun (denoting a feminine gender, or the letter ‘t’), the white crown of Upper Egypt, and possibly a cartouche. The enigmatic title ‘Master of Secrets’ may well refer to the jackal-headed Anubis.

Provenance
Mr Ezeldeen Taha Eldarir, Egypt; acquired 17th June 1941 from Salahaddin Sirmali
Private collection, New York, USA; by decent from the above

Oh, please....

Update 10th July 2020
In a move that might be taken as indicative of how much Charles Ede stands by the assertion that this item  had licit origins in an "old collection", the firm has now deleted the page depicting this item that they had in their stock. It's in cases like this that one can get an impression of how firm the people profiting from such sales in fact believe the evidence is that the objects are kosher and how carefully they vetted the proffered background story beforehand.
