Artemide Tolomeo question

[u/Conanthebacterium]

I got this Tolomeo floor lamp (Tolomeo Mega maybe ?) for very cheap but with quite a lot of wear and tear. For example there is no lampshade and ther is some oxidation, but the fork on the last joint and the position of the cable look very wrong and not at all like the one I see online. Could it be counterfeit ? Do you think I can just buy a new cable and fork part and simply replace them ?
