Beautiful Epi! Unfortunately, as with Phals, Catts, and other much-hybridized groups, you'll never get a reliable ID since siblings can vary and there are probably dozens of greges from which this could come... If it's fresh from the grower try unpotting it to see if there's a buried tag or if the pot itself has a name on it.
Thanks for the contributions though seem to have found a name off ebay; EPIDENDRUM BUTTERBALL 'BEACON'
Just because it is on ebay does not mean that it is correct as you say Nat though am happy to let this ID go now & have told the friend that this is what I have found.
cheers allan
