These are pics of the Shahe DRO I fitted to my lathe. The lathe is a Optimum Maschinen 280 x 600. Of course the longitudinal feed is more like 500mm so I fitted a 500mm length DRO.
The only parts I had to manufacture were spacers to fit behind the standard clamps, a coolant splash guard and a reader bracket which is attached to the carriage. This bracket is in two pieces, I opted to run the bracket below the DRO and then up to the reader so as to stop coolant dribbling down the bracket and onto the reader and bar.
