Hi Tony, 34's chassis is a pair of GBL 57xx chassis cut and shut. The smokebox and boiler are from a Mainline Dean Goods cut so the dome is closer to the front of the loco. The cab is from a GBL C class with scratchbuilt side overlay/tanks. The bunker is cut and shut from a pair of Wrenn/Hornby Dublo R1 bunkers.
Hope this of use to you!
