Small Scale Military Headquarters

Just got a Fedex Pre-delivery notice from Cyber-Hobby for the E-100 (60169). Be on the lookout.

Mr. Football,
Can you give me a brief description of what the Germans actually manufactured of the E-100, and how many prototypes there were?
Is the E-100 the same tank as the "Maus" (German word for Mouse?).
I have a sinking feeling that the Master Nazi at Dragon Models/Cyber Hobby is going into dementia, and this sick individual is trying to sell us every tank that Hitler ever imagined or devised, whether these outlandish Panzers were ever engineered by his subjects, the German people.
STRYKER

I forgot to mention that I own over a dozen 1:72 Dragon WWII German panzers, plus some 1:144 Dragon panzers.
So I'm a guilty consumer as charged!

In the beginning, Dragon Models kind of made a name for themselves by offering weird variations of German weapons not covered by other model makers like market leader Tamiya. This is just a continuation of that niche...

Well, I did my own research, and for those members of this forum who are interested:
1. Pz. "Maus" was a huge 188 ton vehicle designed by Porsche with a huge turret that housed both 128 mm and 75 mm coaxial guns. Only 1 prototype was built, along with an extra chassis/hull. The prototype was blow up shortly before Allied forces arrived at the Porsche factory. The turret was later placed on the extra chassis, and this "vehicle" (which is really an empty shell) is now on display at the Kubinka Tank museum..
2. E-100 "Tiger-Maus" was a 100 ton vehicle designed by Adler, eventhough the turret and armament was to be the same as the Porsche Maus. Only 1 chassis/hull was built, with no turret available for prototype completion. The unfinished chasis was discovered by American forces in the Paderborn factory in March, 1945.
