On the workbench is a Great Western Barnum which I am building from an old Mallard kit. It will be in the BR0 raised firebox without dome format which 3222 sported around early 1910. The Mallard kit features the extended smokebox which a couple of the engines received shortly thereafter. I do not find the extended smokebox attractive so I had to chop a certain amount off the front of all the frames and footplate. This is quite a bold move as complete kits of these fetch large sums on eBay.
The chassis frames are Alan Gibson which I think I did as a special order some time ago:
Assembled chassis frames.
The raised firebox needs a new cab front with the portholes pitched higher to clear it. As I have no drawing of the front of these locos, I botched one together, stuck it on a piece of brass and cut it out.
I had some Belpaire formers in my spares box which I cobbled together to create the raised version. I have no idea where these originated and even if they are GWR but they will do.
Firebox, boiler and smokebox sub assembly
Current state of play. The wheels are Mike Sharman. I will fit the rear axle when I know for sure that the High Level RoadRunner gearbox will be a good fit up into the firebox.
