At one point I sold a lot of Michell TTs, when I was at W. Darby in St. Albans John M told me we sold more of them, mainly, the Focus I admit than any other dealer. The solid platter was indeed an upgade, i not in the looks department it improved things sonically. The greater support damped the record, this gave better tonality and imaging. That's why John used a solid platter with the pretty weights below on the Gyro.
Easy to set up, I think the arm is a Focus unipivot, these were not bad and worked really well with a JVC Z1
