Guess the Tank (Non-Pic)

Hey all, so this is a little game where you guess what the tank is that i'm describing and if you successfully guess it becomes your turn to describe a tank and then the person who guess's yours correctly becomes there turn and so on. At first the description will a vague and hard to guess but as time goes on i will add more details.

Rules:

• Has to be a tank of the early 20th century 1900-1950
• Cannot guess multiple tanks on one message or make multiple guesses in a row.
• It can be a blueprint tank( designed but never made) or a cardboard tank (Tanks in prototyping stages but never mass produced) but cannot be a propaganda tank (Fake tanks designed as propaganda such as the kv-6)
• Try to use own knowledge and not wiki bash
