V. Tan Chay Yan is very well possible, but Vanda JVB is also very well possible when i look at the semi-terete flowers....

Absolutely, Peter If you look at the various hybrids with V. JVB, many of them look just like that too. That's why I believe it is impossible to ID a NoID hybrid.
Do a Google search for Vanda TMA and look at Orchidasia web site. I have both Vanda TMA and Vanda Josephine Van Brero. I am pretty sure that your plant is one of the two.
