However, there is a story that concerns the main armament of the Maus being changed by Hitler who said that the 128 mm gun looked like a 'toy gun' when compared to the tank, causing the 128 mm to be replaced by a 150 mm gun.
Namun, ada cerita bahwa Hitler menyebut persenjataan utama Maus terlihat seperti "mainan" jika dibandingkan dengan tank itu sendiri, karena hal tersebut meriam 128 mm diganti dengan meriam 150 mm.
