Nice pickup original paperwork 
I purchased a set of CPR plastics i just thought that they got the colours wrong ..
Interesting observation.
I have three Flash machines and all three have different coloured plastics. If I take the left sling from one game and place it on one of the other games it looks different. I took all three games' sling plastics aside and no two are the same. Tomorrow I will try to match the CPR Repros with one of the three games. I'll bet that the repros won't match at least two of the original sets..
Same issue with Bally Star Trek. I've had six games next to each other and I struggled to find two sets EXACTLY the same.
I have 4 sets of plastics including the CPR set ..
some have more orange in the red
bolder black outlines and in lettering ..
skin colour varies a lot
The only one that looks the same as CPR is Ivo's Flash
