Good to see another 1/16 Maus project!
Keith Graybeal of ACE Club ran his Maus at Danville from 2004 through 2006, but I have not seen it since then. He used a King Tiger chassis. Maybe he has build photos to share.

I do have one photo of Keith's Maus in combat at Danville in 2004. As you can see, it took a mob of other tanks to encircle it! www.lowell.to/posters2/tankbattle2.jpg
