If you can I will reconsider my commengts but until then, as I said, this looks like no Benoni I have ever seen.
OK, I accept it is something of a theory avoiding sideline - and just so happens one I play OTB. In fact it could be called a Queens Gambit Accepted with the colours reversed if Black plays d5, and some lines of the Qc2 Nimzo Indian will transpose. It warrants a footnote in Nunns Chess Openings but I have an early example by Marshall see below. I suppose it is an (old) Benoni by virtue of the 1...c5
