Hi Lee, The next time I am at my garage I shall take some photos for you although CSJ 655 was a complete wreck when I acquired it and it only has two holes for gauges in the dash. I have fitted a 30 ampere gauge in one and an hour counter in the other, mainly because I had one that was the right size. It almost certainly wouldn't have had an hour counter originally though, I would have thought an oil pressure gauge would have been more likely. Switch wise, again everything was missing and I have a key operated ignition switch, which whilst not original is a good idea on the rally circuit as the whole vehicle is open and very attractive for children to climb on. It also has a foot operated starter switch mounted through the driver's footplate which is an original feature and for this reason I have fitted a kill switch on the battery. Everything by the way was fitted in to existing holes, and because I ran out of original holes I fitted a lamp switch on the new seat box. Interestingly, I did acquire the remains of another Mercury truck years ago to help with the restoration of this one which not only had front wheel brakes but also a speedo rated to 15mph, driven from one of the front hubs. It was from this truck that I got the radiator and numerous other parts like the double rear wheels all of which were missing from mine. What were you expecting gauge wise? Pictures to follow, although you will have to give me time to get them as the vehicle is stored near my parents house in Kent. At least I will be able to tell you what is original on mine and what isn't. Did you find a chassis number? Mine is on a brass plate on the front left hand of the chassis. You can see it in the photo above.
All the best,
Adrian
