Hi over the last few months i have bought a few lamps. i have only been able to identify one of them. hope you guys can help me figure out who made the rest of them.
Here is the album with all the lamps. look in the photo description for info on them.

Gispen?
I think the last of your 3 lamps could be Gispen. The stem,the base and the small ring, together with the bakelite(?) handle on the stem are very like the model 5020(1936?-1960). However the shade is different from the earlier model. In 'W H Gispen, Serieproducten 1923-1960' on page 36/7 it does talk about from 1948 the shade being of aluminium and rolled at the edges. I hope this helps.
I'm no expert
but the details of that "Cocotte" look wrong to me.
Most obvious is the swivel joint. Mouille's swivel was an important part of the design, and he made it smooth and almost organically shaped to complement his lamp shades. The swivel on Manp's lamp appears to be very different.
The connection between the body and the legs of Manp's lamp might also be different -- maybe the body sits too low between the legs? It's hard to tell from Manp's photo.
As I said, though, I'm no expert.
