Still meaning to get round to posting pictures of the 'brat's flowers opening... still not got time! But had to post some news of various trails I've been following. I found a site with it's parentage:
translated German site
Still no luck on RHS...
But looking up parents, found the Miltonia may be moving to Oncidium.

The first spike has just finished. Second spike currently just opened, though a couple of flowers blasted. Looks like there may be blasting on the third spike too
Oh well, still a nice plant, and happy to have a proper name for it now! Though there's still the Toscane or Toscana question I guess!
