Mellotronists

Greetings to all!

A few weeks ago, I posted requesting opinions about GForce's M-Tron 
softsynth (thanks for the replies!).  I just got it a few days ago, 
and I am loving it.  Lots of cool sounds, and some really great 
rhythms!  Next, I plan to buy the Mike Pinder sample CD.

Also, today I had a long discussion with a guy who has long been 
involved in the local (Tulsa, OK) music scene.  He was telling me 
about the 'Tron that was in the Shelter Records studio in the early 
70s.  I'm going to do some detective work to see whatever happened to 
it.  It was white, so I am assuming it was an M400, correct?
