A Myaskovsky Clarinet Concerto?

[eschiss1]

Worldcat lists a copy of Moore's clarinet concerto here if this helps at all...

Just as an update I got a response but it was to re-direct me to a different outfit that I was advised hold the actual physical materials (recordings, scores etc) rather than just the digital info that BMC hold. I have re-posed the question there. I am hopeful I will actually get a response even if not the actual answer to the query.
