So this weekend see's me working on a new chassis for a GWR large prairie tank in an effort to create something differ3nt but also similar.  I imagine this could have been a possibility although I suspect its light weight would have been useful, the real GWR might have made one on a longer chassis? This was largely inspired by the LSWR Urie tanks, the driven wheelbase is 6'6" + 6'4" like the Hawksworth 1500 class pannier tanks, with the same 4'7.5" wheels.  I suppose my excuse is that its a freight tank loco but in reality I love the look of narrow gauge locos, the proportion of the body size to the wheel size but don't really want to venture away from 4mm.
