...a Basilisk with a Leman Russ?
This is the first of my two artillery pieces; I have combined the hull from the Basilisk with the track units from the Leman Russ. I was looking for something a little different, and with Bits and Kits selling the tracks for £2.50 each, this was fairly cheap. I will find a use for the Basilisk track units somewhere, I'm sure.
Quick and easy, and it looks a bit heavier than the standard Basilisk without being so different as to confuse my opponent.
