need help on Taito Vewlix C Capcom + Taito Vewlix L AMI urgently

Hi,

I am about to inspect the below two Taito Vewlix Arcade Cabinets at one of the local arcade here.

1) Taito Vewlix C Capcom

2) Taito Vewlix L AMI


Can the Vewlix experts please list down all the things I need to check to make sure each of the above is an "Authentic" Vewlix Arcade Cabinets from Taito Japan?

Also how do I tell that it is not a cheap china copy?

Thank you very much for your time
