I believe that there was a ammeter in the tank panel right side also a light on the left side, which came on with the lights but could be pulled up and swivelled to see other gauges, interesting to see the carrier with one bar across similar to the ones I am selling, mounted on the mudguard. Ron the number plates, as I remember were always this way round, I believe it was the army that change them to an elongated version to accommodate the numbering system ie two letters two numbers and two letters, keeping the whole thing neater.
