Gun from a yamato 1/60 tomahawk Olive Green
 

Have you got a yamato 1/60 tomahawk Olive Green that you broke or otherwise are not happy with!?

I want you to tear off its gun arm, violently and sell it to me! (after beating it with its own gun).

Now I have your attention:
I am looking for the gun barrel from a yamato 1/60 tomahawk in Olive Green. I love my little mech but at some point I misplaced one of his barrels.
