Holy moly, I may have found the holy grail of WoT-extracted paper tanks!
Worldofpapertanks.com
It's in Russian, but in browsers like Chrome you can auto-translate to at least make it intelligible enough to poke around, and it -seems- to be the original source of the P.1000 Ratte I previously posted.
There is a seemingly nice model of the Maus (better than most of the kits as far as textures goes really!) and even an E-100 in desert camo and it has some really good detailing in the pictures I've seen...

Get it while it lasts, it -may- be made "for sale" at some point, I dunno because I can't really determine what the plans are for it on their website, but for now, it's free on the Russian World of Tanks website, and while the instructions are all in Russian, it appears to be a simple shape/build so the pictures in the instructions should be sufficient.
Maybe in time more of the models in-game will be uploaded to their message board and we can all have fun with them.
I don't see any convenient way to get the models, and from what I can gather through my VERY VERY VERY basic Russian-to-English, I think the idea is of course for their developments to go up for sale at a website store, but I have no idea how to find/access it if it even exists yet...
But it is at least a start and they seem to have a bit of a production going on and might get a lot of the WoT tanks into real life which would make me plenty happy.

Figured out a little more on how to get -some- of their older models, including a neat KV-2 and an IS-3 plus some miscellaneous light tanks which would be cute and fun to have around as well.
You HAVE to click the pictures of the model you want and it -should- go to a viable link to download them. But again, get them while they last, anything good likely won't last...
