[Boatanchors] Restoring a vernier dial

[Dave Sublette]

I am really new to the art of restoring boat anchors and I need some
advice.  I have a National Velvet Vernier dial that is over 50 years old.
It turns smoothly, has no backlash and stays where I stop it.  My only
complaint or concern is it takes a fair amount of force to turn it.  It is
not one of those dials you may spin to reach the other end of the band!

The unit is a small one.  The dial front plate measures 3 7/8" by 2 3/4".
The tuning knob is not quite 1 1/2" in diameter.

A couple of questions.

What , if anything, should I spray into the insides of it to clean and
lubricate it?

2nd...  The chrome ring insert in the knob is rusted,  Any thoughts on how
to restore it?

3rd  The black crackle paint is worn off.  I suppose I can buy a spray can
of it to repaint after I sand it.  If so, which brand.

last ... The cardboard logging scale is in need of replacement.  Does
someone sell these, or should I get on the computer and attempt a
reproduction?

Thanks for any help that you may have for me.

73,
