I've been a helicopter enthusiast since childhood (I'm 58) and I have never heard of a Del Mar DH-20 .

A Med-Evac, was news to me as well, doubtful we're alone in not knowing Bryan.
I thought it was some type of heavy lift till I saw the pilots seat up front.
No doubt there are a lot that are now lost to history.
Saw this on YouTube, shows some close up, what an interesting albeit weird design.
