I have a set of 125mm Vixen tube rings. These will fit the Tak FSQ106 perfectly, as well as of course Vixen's own larger refractor tubes and others. Colour is white.
These are absolutely new, though I did remove the hand tightening knobs and installed plain capscrews, as the knobs interfered with a Losmandy plate - they no longer interfere, and also fit a Vixen bar perfectly of course.
New is here:
