Dr. Luchy's Vision was not realized until after the apocalypse when resources were few & only the remotest parts of the world yielded the vast numbers of fuels, minerals, etc that were needed to put the world right. There are vast fleets of these steel, aluminum & composite behemoths moving across the face of the planet. They are even now reclaiming the burned out cities, the radioactive wastelands, & other areas. These mechanical monsters are crewed by only the very best men, mutants, & scientists that the world has to offer. 

Pirates & other scum who think that these are easy pickings are in for a surprise most often the outfits that run these beasts also have 1d30 X10 mercinaries on the pay roll as well in aeroplanes & scout areo piles 

 There are 3 of these mechanical monstrosities that are under the control of pirate lords who use them to not only raid reclaimed cities but to boost the economies of their own city states as well! There are those who claim that these monsters have been seen as far as the great unclaimed shores of Forgotten France & even Lost Russia! 

Other OSR Uses 

These mecha could show up in the annals of an inter dimensional campaign as those that have been talked about here or even a Post Apocalyptic Mars! The use of these on a space opera isn't out of the question as planets out in the Outer Rim of the Galaxy use low cost solutions to reclaiming lost resources. 
For a Labyrinth Lord or Crypts & Things game this mech provides a perfect fodder for something very different from the usual dragon's lair & its wrecked hide could provide the perfect topping for a mega dungeon! 
The Original Source 

The original source for this article was Io9 right Here with the following explanation 

Dr. Luchy, who has been collaborator with the Chevalier Pini, the inventor of astonishing machines for exploring the sea bottoms, asserts that if Captain Scott had been equipped with one of his mechanical mosquitoes he could have made his way to the South Pole within a few hours after leaving his base. He also claims that the machines will make impossible any repetition of the Scott tragedy, and will enable man to wrest from the Antarctic continent its mineral treasures without exposing their operators to the slightest danger [...]

Only small working models of the mechanical mosquitoes have as yet been made by the inventor, but these seem to be as practicable as the paper plans promised. A large working model forty feet high when the long, articulated legs are fully expended, is now in course of construction. In the body are the engines which, provide its motive power and the quarters for a crew of ten men.

I 'd like to thank IO9 for providing me with yet more fodder for my campaign!
However the original article from 1914 from a Utah newspaper goes into much, much greater detail! The article has a pdf function & I suggest you download it & read it! Its well worth it. Read it Here
