Sorry, that's wot I meant! Got it asc about desc... Nice machine, love to see it, think the engines have those lovely noisy augmented exhausts...
Edit: thinking it through further, Excalibur reminds me that it also step-fathered, via the Excalibur Queenair and Merlin II, the Merlin III and Metroliner though I think they share no common parts with the Beech designs.
