Novoflex follow-focus lens

[pgs@thillana.lcs.mit.edu (Patrick Sobalvarro)]

So I got this 400/5.6 Novoflex lens for $295 from Alkit Pro.  Good
price, and the lens appears to be in excellent condition, but I can't
try it out until the mount I've ordered arrives from Germany.  I was
thinking I'd go down to Ano Nuevo and take pictures of the molting
male elephant seals, which one can't get very close to for obvious
reasons.

But I had a couple of questions.  First, there is dust on the glass.
It's on the inside, down this very deep barrel.  This lens is a
triplet, very similar to the Leica 400/.6.8 (which is however a
doublet) in that the elements are located at the front end and the
rest of the lens is hollow (well, there's a diaphragm, of course).
Does anyone have any suggestions as to how to clean it?  My usual
approach to cleaning lenses is to do it as delicately as possible.
I do all those things like blowing on it first and then using a
camel-hair brush very lightly and only then using lens cleaner on lens
paper, again very lightly.  But how do I get at this glass?  The front
of the lens is removable, but it's still maybe ten inches long.

Second, I see that there is a tripod screw in the bottom of the
follow-focus grip, but it seems a bit insecure to mount the lens on a
tripod through the grip.  Is the grip removable?  I don't see how it
would be, right off hand.

Thanks for any advice you can give me.  I do very much like the lens,
with its all-metal construction -- it feels as solid as any of my
Leica lenses.  Perhaps slightly less refined.
