A good looking piece of equipment for use or display. Comes with mounting plate and 2 holes so you could put it in a dash as well. Seems to be all complete and very clean. Set to measure speed in Km/h . Signed N.V. Observator – Rotterdam…dus instruments manufacturer and it has the Dutch Railways (Nederlandse Spoorwegen) blue-white logo decal on the back. Not tested. The dial / face part measures ca 10 cm or 4 inches in diameter, little more with the mounting ring included. All the lettering on the gauge is in great shape and there are 2 small catches for the hand at start and end. Check out the video from the Tool Man himself (1990’s series with Tim Taylor).
