If I may interpose here chaps, and add another wee conundrum, I have here an ancient 1961 'Aeromodeller', which has a photo page '...taken at the 1961 US Nationals.' there, along with Tom Bretts' original 'Nimbus' is this machine, in what is obviously Ed's favourite colours. It cannot be a modified Taurus as we know it, but is it possibly the link between 'Orion' and 'Taurus?
