Unknown Stealth Wind Tunnel Model

[Dynoman]

Unknown model. It is identified as a wind tunnel model for a stealth aircraft on Alamy photo archive. Any information on this design (manufacturer, model number, etc.)? It looks to me to be more of a display model.

Reminds me of the Lockheed Next Generation Bomber Study

A very small wing, maybe hypersound...
