Possibly a Brama-Hansa lamp. Some pictures of the burner might help. That type of lamp head was used by Brama, Blanchard, Hasag and Kitson so it could be by any of those but I would expect Brama or Kitson most likely. It's a very interesting lamp. Are there any markings anywhere on the parts? ::Neil::
Nice looking lamp Migwar Looks like there is something stamped on the pump knob Neil but i carnt make it out Cheers pete
The pump knob, as @pete sav said: It looks vaguely like the Turner logo, but whatever it is I think it is a strong clue. Tony
Nice model. It is modified so, some pictures of the burner head without the not ooriginal Px hood would sow if the burner is still original. If so: a very nice rare lamp.
