Center stand is a Plateau. 28 stands are homemade, just this past weekend.
FYI the adjustable spike, sonically neutral, low resonance, vibration dissipating, audio quality legs are the spring bonnets off of old pressure regulators. Glass beaded to stress relieve and align the molecular structure, and painted. Kidding aside they worked great, and you could probably support James Beamer with them, which might be only slightly heavier than the 28's.
