I've looked into this a bit more and tend to agree, due to its lighter tones it resembles the wallisii more. I've also read in a few books "caudatum var wallisii". Its getting a bit complicated but I need to confirm its identity asap, so any further help would be great.
Thanks

Very nice!
I will tend to agree for a warcewiczianum, I did get a plant like this one from Ecuador as caudatum var. gigantea ‘Special’ but special was just for the more expensive price. I did bloom it side by side with my warscewiczianum (wallisii) and was not able to see any difference!
