7Q5 Redux

A few weeks back there was a brief discussion about 7Q5 (and O'Callaghan's
--discredited-- identification of it as a fragment of Mark).

At that time someone made a reference to some work (their own?) which
showed that there were several places in the LXX which the text of 7Q5
matched better than the purported passage in Mark.

I seem to have lost the message in question.  Does anyone remember this?
Can you provide a specific reference?  


P.S. Does anyone know a (easily-accessible) published photograph/facsimile
of the 7Q5 fragment? -- N
