Looking to identify this PH-style lamp  

Hi,

I have bought this lamp in a vintage shop in Denmark. I am having a hard time identifying it since there are no written clues (brand name, model name, serial number). I can assume that some info was provided on the label but it turned old and yellow to the extent that nothing can be read from it.

I don’t expect it to be anything super valuable since its build quality is not outstanding, but I’d really want to identify it. Let me tell you what I know:

- it’s most likely vintage (the yellow label looks like at least 30 years old)

- the lightbulb socket is made from plastic.

- the cable is in some kind twisted thick string while the lamp is hanging on a strong string which is attached to a device that allows for adjusting the height at which the lamp is hung (rolly)

- the uppermost cloche is something I cannot seem to find in any similar models

- the lamp is made of metal and rather heavy. the outermost diameter is 50cm, while the height is a bit less than 20 cm

Thank you!
