K3 VFO A knob problem

[Ken Kopp-3]

The shiny surface inside the finger dimple of the large VFO A
knob is "peeling" off in small thin pieces, and is now about 50%
gone.  I'm not aware of any chemical associated with my index
finger ... other than perhaps dirt. (;-)

Anyone else noticed this?

Fingernail length?  Mine has no issues but I don't tune all that much using
the dimple.  I do the Coarse and spin the dial when checking out a band.

Thought of that, Bill but I don't think so ....

I've had/used the radio a couple of years (S/N 56) and
the peeling has just started.  My nails are pretty short,
and rounded, without sharp edges that would tend to
"dig' into the surface.  It looks like there's a "shiny"
veneer surface that's peeling off and leaving a dull plastic
surface inside the dimple.

 Yes,

I now have 2 K3's #806 and #1055 (bought used).  #806 exhibits the
anomaly you describe, but #1055 dies not.  However #1055's dimple edge
has a metallic shine to it as though it was not painted.  I think what
I am seeing here is that #806 has had the dimple painted, but #1055
has not.

Perhaps different knob suppliers in the past?
