Which Dendrochilum is this?

I know this is a horrible pic (took it with my phone) but does anyone know which species this is? the plant is about 8 inches tall and the inflorescence measures a about 12". I've had this plant for at least 10 years. it was a gift from a friend and he told me it was undescribed at the time. it did have a tag with some number code on it but that was lost a long time ago. Any thoughts?

 

Thanks for the suggestions. This plant is much smaller than cobbianum and billacosum. It is on par with uncatum in size but from what I've been able to glean, this seems to be a different plant. I'll dust off my macro and flash tonight and see if I can get some clearer shots of the flowers. my photography skills are in deep entropy though so we'll see what comes of it.

 

Thanks Marni and Boytjie for your input. here is a close up shot of the flower. I should also say that I put a ruler next to the plant and it is smaller than I estimated. The plant height is 5 inches from base of pseudobulb to tip of leaf. the inflorescence is 8" in total length.
