More Information
Lords: Some wear to the plating on the case, especially on the adjusting knobs, all three of which work smoothly (see update below). The glass appears to be free of unsightly scratches. Update to condition report 26.7.24: the lower adjusting knob on the right hand side is tight, then goes a little loose at 70, 55, 30, 17 and 11 on the outer calibration ring.
