VECTOR: Black Widow CPO differences?

Hi all.

I recently picked up a bare Black Widow control panel (well, no sticks, and 
no buttons, but the wiring was intact).  Anyhow, the overlay at the time of 
purchase had several globs of what looked like paint on it so I figured I'd 
grab a replacement overlay and restore the CP all of the way before 
installing it.  The repro overlay arrived yesterday and looks stunning.

The only problem that I have is that my control panel overlay varies a bit 
from the repro.

1. The instruction box on the right side on my control panel is blue.  The 
same instruction box on the repro is green.

2. The web grid "rings" on my overlay are also different from the repro.  It 
has the following ring colors (from outer edge inward):

blue, pink, orange, blue, blue, pink, yellow, blue, blue, pink orange.

the repro has:

purple, pink, orange, blue, purple, pink, yellow, green, purple, pink, 
orange


Any ideas on why the color differences?  I pulled out pics of the Black 
Widow I owned back in '96 and it had the normal green in the overlay the 
same as the repro and the ring coloring is the same as the repro..  I am 
stumped.  It does not appear to be caused by fading either.

Here are some pics.  Notice that the paint globs are gone from the used 
control panel, I was able to get the paint off by using a small brass wire 
brush.   :)
