Is this a twinkle?

[mascia]

Hi,
I got a no id oncidium from a friend some time ago, and now that it finally has flowered it looks and smells pretty much like a twinkle, except its bulbs and spike are 3 times the size of my actual twinkle.

Here's a picture of it. For comparison, the smaller bulb in the front is about the same size as my twinkle.



And the flower:


This is my Twinkle 'fragrance fantasy' which has almost 20 bulbs and 10 spikes right now. You can see how tiny the bulbs are.



I also have the red and yellow ones, and both are about the same size as the fragrance fantasy. Do you guys know if what I have is just a huge twinkle or maybe something else?
