Mellotronists

Another Tron related link.

Obviously Mellotron samples used here... or? an emulated Mellotron Vs 
actual samples? P. Tree lists a use of a Mellotron on recent studio 
records but I wonder if Richard Barbieri(keyboardist) sampled thier own 
tron or is he using some comercially available Mellotron samples?  

Anyone have ideas or knowledge about this?
