It's a coincidence you mention that, as Velocity VR was also running Vive. Not sure on how old it was though. But the headset and controllers definitely had the Vive logo.
It's quite unlikely Velocity VR is using the original vive headsets since they aren't manufactured anymore. You probably used to vive pro: https://www.vive.com/us/product/
I get that, I really wanna get the Index but I can't afford that so I'm running on an old Vive
