Cheers Discorde!
Rather taken with the image of the Beechcraft 120, a turboprop Queen Air with Turbomeca Bastans... The resemblance to the Swearingen Merlin II which a new fuselage sat on Queen Air wings (and was a progression from his Excalibur QA modification) is quite marked!
Edit: just looked this up in Rod Simpson's book, pic must be a mock-up as the prototype was never built.
