Here are some photos my brother sent me of his progress on this project recently. You may correctly deduce he is a better engine builder than me! Will try and get more as he moves it along. Pete.   |

Hi Peter,
These are useful photos to show just why Churchward fitted that BIG boiler support plate........As you can see the assembled cylinder / saddle unit is bolted onto the mainframe at the rear--- and bolted onto the frame extention plates at the front.........This method allows for the cylinders to be removed from a service loco without having to remove the boiler, which then rests on that support plate......
The 49xx Halls had the same set-up, whereas the "Modified halls" had a one-piece mainframe with bolt-on cylinders --- much like we do in the smaller gauges...
The Stanier Moguls ( Princess Marina in 3.5" gauge ) have their roots in these locos........I have a 5" gauge GWR one and it's almost like driving a shorter version of the 4-6-0 Manor...
Some lovely work there by "Big" Brother ??
Can you ask him if those piston valves are of the "Semi-plug" type as per full size ??--------maybe some close-up photos if possible-------I used to make and final assembly those at the SVR on contract work.........
