the design is preety simple and fine details wouldnt be to hard to stamp out but there are easy and hard ways to do it and once you know what you want it would be perty simple to make a set up like that
couple of hinges , a pump , ram , some steel and a some simple design,
and from looking at the picture it seams to be a show truck or some thing for showing off so leaks , crud and other stuff wouldnt be a high priority as it would be cleaned offen and covered the rest of the time
