No doubt, at the expense of losing a short distance at each end of the bed, brackets could be made up to carry the DRO scale, clear of the Saddle.

The C1 has the advantage over the C2 and C3 of having T slots in the Cross Slide, but obviously is a smaller machine. Various owners have made a new Cross Slide for their C2 or C3, incorporating T slots.
