Mislabled Oncidium of some type?

[megrim]

I purchased this guy last year, clearly labelled as a Miltonidium Bartley Schwartz 'Highland', as I'm a big fan of fragrant orchids.

This year it has begun to flower nicely, and most certainly not what it was labelled as. I'm assuming it's an Oncidium, or something within the general vicinity of - just wondering if anyone could shed light on what particular variety it might be, or indeed if it's just a generic mutt?.

I'm not too upset - I've always loved copper, orange and earth tones in orchid blossoms, so it's still a lovely plant - just not at all what I was expecting.
