Bottom right is Hobby Fan's IKV-91 amphibious tank hunter. Light weight, light armor, 90mm gun.
The Maus is mostly out of the box, I changed out the main gun barrel to the 128 from the Pak 44 (?) and am trying to add a Panther Cupola but I'm missing the hatch.
No problems building it. If you try one, be very careful aligning the panels.
I'm a little concerned about getting the tracks on later
This is what I'm aiming for
