Porsche received on 21st of May 1942 the order to produce a 100 ton Panzer. The initial name for the project was »Mammut« - the German word for mammoth. This was the natal hour of the Maus, the first documented reference of “Pz. Kpfw. Mäuschen” was the 17 of July 1942 ... 
Only 2 and a half month after receiving the order Professor Porsche prepared the first design drawing on June 4, 1942. It had the number K 3381 and was done by Ing. Leopold Schmid. The designation from Porsche for the project was “Porsche Typ 205”. The drawing showed a streamlined tank with up to 120mm armor and 120 tons weight. 
波尔舍教授在接到命令后的两个半月内，也就是在1942年6月4日，就完成了第一稿的设计图。图纸编号K 3381，绘图者是工程师利奥波德·施密特。波尔舍给此项目的代号是：波尔舍Typ 205。图纸上画的是一辆有120mm厚装甲、120吨重的流线型的坦克。
The turret’s weight alone was 23 tons, carrying a massive 15cm KwK L/40 – with some modifications done to the ammunition. The weight of the projectile was decreased from 43kg to 34kg to increase ROF to 4-5 rounds per minute and the muzzle velocity to 845 m/s. As an alternative, a 12,8cm L/50 with a muzzle velocity of 810 m/s was also considered during the development of the tank. 
炮塔重23吨，装一门15cm KwK L/40巨炮，对弹药做了一些改进。弹头重量从43kg减到了34kg，将射速提高到了每分钟4-5分，炮口初速为845m/s。另外，在研发过程中，还将炮口初速为810m/s的12.8cm L/50炮作为备选。
The powerhouse was driven by an air-cooled 16-cylinder diesel engine, with a comparable propulsion system to that of the Tiger (P) – every track was boosted by a single electrical engine. The ground pressure of the vehicle was 0,92 kg/cm². There was also a shortened variant of the blueprint of drawing number K 8331 . This one however hasn’t been discovered yet.
This is what we currently know about the earliest of the Maus’ prototypes.
Further values I can read out of the book  (without guarantee, the drawings are still too small to read most of the values) - just to give a rough idea of the vehicles armor values. Armor values are based on interpolation, and the assumption that the confirmed 120mm  are on the front of the hull.
以下的装甲数据来自Michael Fröhlich所著的《Kampfpanzer Maus – der überschwere Panzer Porsche Typ 205》一书(但不保证正确，图纸太小，很难看清大部分数据)，只是一个大概的值。数据是脑补的，假定车体前部是120mm。
The upper front plate is sloped back at 55°. The lower one is at an 45° angle, both are just as thick. Effective armor values with current World of Tanks “normalization” are 187mm and 157mm respectively. The upper side armor is sloped back at 20°, the lower one is vertical with the tracks and another plate with 40-50mm behind them. The rear is as thick as the sides and rounded.
The turret front is just as the Löwe’s covered by a huge gun mantlet. The turret sides are very thick possibly even ticker than the frontalarmor.
This might also explain the weight of 120 t, the armor is all round pretty good and not much thinner than on the front. The size of the vehicle is comparable to the E100, just a lower profile and maybe a bit shorter.  However it’s still quite a bit smaller than the tremendous Maus.
The gun depression is 7° - with the assumption that drawing K3882 shows the same gun depression.
