If that's the Churchill AVRE (Armoured Vehicle Royal Engineers) it's been out for a year or so. Picked mine up when it first came out, very complex working running gear that will take a lot of work to get right but looks like a really nice kit overall. Now if I can only find some time to build the thing.....
I believe Masterbox is coming out with a set of British sappers with mine clearing equipment that would look great with her.
