For sale are Smiths brand black face tachometer, speedometer & holder for various 1970's British motorcycles. $80 plus shipping.
The speedo works well, past 100 mph+ (Triton tested...), but odometer trip knob is missing. The tach worked when I bought it, rode it for 20 miles, it stopped working and I gave up. Also included are the wires, bulb holders and bulbs (not pictured). Not for a show bike but will work on your rider. Take a look:
