Schottlander x Arteluce
Hi There,
Does the Arteluce catalogue have a date? / of you still have it would if be possible to post a pic of the Mantis table lamp?
Thanks on advance for your help

Here is a pic of a...
Here is a pic of a Scottlander table lamp from Illuminazione D'oggi. Not exactly the same as the Mantis-but very nice nontheless. Maker is listed as "M.S.I.A Londra"

I actually saw a Mantis...
I actually saw a Mantis floor lamp produced by Swedish company Bergboms a couple of years back. Yellow shade and white base if I remember correctly. Bergboms was the company who also produced the Swedish version of Greta Grossman's Grasshopper lamp, among many other nice lamps.

Londra
is, of course, Italian for London
Not sure what M.S.I.A is though... an acronym awarded the designer, rather than a maker, I think. (The Dis. being an abbreviation of disegnato, meaning designed)
Nearest possible I can find is Master of Science in Industrial Administration

Thanks Paulanna-certainly make sense. Attached is a shot of the re-issue version of the Mantis table lamp. I think the floor version works better. I prefer the base above for a table lamp. The wall hanging version is also pretty cool...but a bit too much mouille-esque for me

NOT arteluce
The Arteluce Mantis lamp is made at a much later date than yours(1980's) and I believe it is a Miranda design. you can google Arteluce Mantis or look here: http://www.kingmiranda.com/en/about/awards/1983-2/
It is purely a confusion. There are actually quite a few models of lamps called Mantis made by a few different manufacturers and designed by different designers at various point in time form the 1950's up to now. Cheers!

Just realized this thread...
Just realized this thread was dead for three years until couple days ago... I hope other folks won't get confused and start attributing the Schottlander Mantis lamp to Arteluce :))

I just posted the info on...
I just posted the info on Bergboms, because I thought it'd be helpful for someone to know that the lamp was also produced under license in Sweden.
I was not aware the Arteluce attribution was faulty. However the Bergboms Mantis really is an actual licensed version of Schottlander's design and manufactured in the 1950's.

There is also the possibility of me being wrong 🙂
