From what I remember the Queens Building had a large scale model of Excalibur maybe 1/4 scale but I doubt it was much bigger than that atop a pole with a plaque explaining the significance of the model.
I don’t think Darryl Greenameyer ever raced Tsunami. He owned and flew the Bearcat Conquest 1 and was later involved with a Yak 11 which first appeared fitted with a T-33 tail unit and a Pratt and Whitney upfront named Mr Awesome. This aircraft evolved over many years but I don’t know where it is now.
Tsunami and her pilot owner were lost when a flap operating rod failed on approach causing an uncontrollable roll. A sad end to a fine aircraft and pilot.
