It's not exact. Not sure anyone ever expected it to be exact.
I look at it this way - would I like an exact reproduction? Absolutely, I think anyone would. Although, with a modern touch, so after a few years, the green hologram didn't turn blue.
But, if you've got *no* hologram, or one that's completely turned blue, you'd be pretty happy to have a similar product to put in your game.
Thanks for making more needed parts, which will in turn save games. Just another *option*.
