ebay.com link: 1981 Bally Centaur NOS Backglass

This is not an original NOS, it's a repro made in the 90's
This is not the first time i saw this error, i feel sorry for the possible buyers ...
I tried to contact the seller without sucess.

I had both an original and this version a few years ago.
Both look very similar from the front, it look like this repro was made with the original method.
The details and quality are better than a cpr for example.

The major difference is the blocklight layers in the details area, it's simple not there and like the cpr version
when light go through the glass it look greyish and not inky black with high contrast like the original.
Check my pictures, all over the black details you can see bumps of blocking lights layer to improve contrast.
If the seller is willing to take the same picture, you will see no bumbs, only a flat surface.
Also you remark that the white layer is thinner as you can see througt is more easily.

I also bought this repro version a few years ago thinking it was an NOS but i realize it was not when i bought an original one, i sold this repro and keep the original of course.

In my opinion the real value of this repro closer to 250$-300$ considering it's a better version than cpr.
