There is an earthing boss in the base bellow year red line. There is no earth continuity between the bottom section and the rest of the fitting. The rest of the fitting is un earthed, the middle section is a fairly thin gauge tube separate form both the base and the lamp.
The lamp holder does have an earth which is connected but there is no continuity between this and the rest of the exposed steel structure.
I don't see any reason that the middle section would need connecting to earth? If it is insulated from the earthed metal parts as you suggest then it presents no problem
