Ultimate Support VSIQ-200B Second Tier Add-On Keyboard Stand Attachment - FOR PARTS ONLY!

This is missing a few knobs that would need to be replaced. Since it is missing parts I cannot put it together to confirm everything is 100% functional, however the only known damage is the level bubble. 

Please see pictures for detail of damage and missing parts.
