I'll agree with that diagnosis. Kind of a rare airplane. Berkeley kitted a model of it, and so did Telasco, I think, for Jetex power. I think there was even a stunt model in Flying Models in the 60's. Easy to understand why it might have been mistaken for a FH-1 Phantom, but the Phantom was bigger by quite a bit. I might have to take a road trip down that way to check it out.
Type at you later,
