Hi Vtl,
You have an older Bright Star Audio Air Mass 2 pneumatic mount. That model is no longer in production.
That model relied on gravity to achieve absolute level. For most components that is not an issue. In your case, your turntable has an off-center load weight because the motor and platter are not in the physical center of the chassis. You can easily compensate for this when setting up your Air Mass 2 by adding some extra weight between the component and the Air Mass as required to achieve a level surface.
I have emailed a copy of the owners manual to you. Please let me know if you have any other questions.
Best Regards,
