It's good to see it all in one piece. Assembly is by no means straight forward, and takes a considerable amount of care and patience. One of the trickiest parts is fitting the gudgeon pins. There is a PTFE pad on each end of the pins and you have to be careful not to push the first pad out of the other side of the piston. This is especially tricky when fitting the second pad as there isn't much space for them to fit between the ends of the pin and the cylinder bore.
