Warhammer 40 K Dreadnaught Kit

 In Warhammer 40K dreadnaughts are not ships but powerful walkers. I bought this one at a bazaar. It comes with the magazine. My intention was to use the big guns on a tank. However, I might assemble the whole thing. I don't follow all the backstories for 40 K but some of you might know more about this than me.
