Mellotronists

Hi everyone:

I have just joined the list, and it's a pleasure to join my mellotronic
passion with you all :D.

I own a Mark VI (#48). I would like to make you a question about oiling
it. I have been oiling my 'tron in the past but never quite sure if I'm
doing it well. The problem is, english is not my native tongue, so the
explanations about the engine parts got somewhat confusing to follow for
me. Wouldn't anyone have/know a picture or graphic schema signaling the
points to oil the 'tron ?

Also, I am using a very light oil I had from an old sewing machine, and
I don't know if it's the proper oil to use in a mellotron. Any idea of
where can I buy a better one?

Hope hearing from you and best regards to all 'tronists.

Nacho.
