This was made after a 1/50 die-cast model of the Schwing S 58 SX concrete pump.
A lot of hours were spent in taking every measurement possible with a vernier caliper, most of the parts are very accurate but I had to improvise where I could not take the measurements or where the pump can no longer be disassembled without it been damaged.

The assemblies have all the mates they need to be fully functional and posable like the actual die-cast model.
