I have this ESB Lando with the POTF Lando General Pilot head. I would have bought this back in the late 80s, like all my figures, so it's not a more recent modification. At first I thought it was a factory error, but I've not seen any other examples, so I guess someone must have custom made it back then? I can't really think why someone would bother doing this custom, though? Seems an odd thing to do...
