    Hi All

    I am currently embarked on building a test build of the forthcoming Brassmasters Coronation or Duchess kit. Way before I got distracted with Brettell Road I always thought that if Brassmasters ever did a Duchess i would have a go at building one as 46235 'City of Birmingham'. Well now they are and so I am!

    Of course its a personal opinion thing but I never really liked streamlined steam locos. While the Duchesses were a little more thoughtfully designed than the god awful GWR efforts I always thought they looked a bit like an upturned bath tub and have to admit the A4's did look a fair bit better. However with the streamlining taken off the Duchesses were 'it'. The steam locomotive version of the Concorde moment. To my eyes, at least, the pinnacle of steam loco perfection.

    Anyway enough hero worship and on to the model. Starting with...

    The main sub-frames. The loco frames come in 3 sub sections related to the wheels. A driving wheel section, a pony truck section and a bogie section.

    The chassis upside down, test fitting the main coupling rods.

    The main frame with the brass overlays fitted.

    The front or bogie area sub-frame.

    More to follow.

    So progress continues on my Coronation build.


    The front frame is as far as I can go for the moment. (I don't have the cast bits for the loco yet. If you are wondering about the cylinders they are a separate sub assembly.


    No problems with the pony truck so far. The kit provides for both the earlier and later types. This is the later one.


    The bogie is compensated. As the bogie is the only part of the loco that traps the wheels in place I have used some old/rejected wagon wheels for the moment. I ideally only want to put wheels onto the axle once if I can.


    Without the wheels in the way.


    I couldn't resist a temporary mock up to see get a better feel for the loco. I've used a High Level Road runner + gearbox. The main drivers don't have their springs in place yet so its sitting a little off at the moment.

    Looks the part Jim, even in 4mm scale.

    What is the purpose of the slanting parts behind the rear driving wheels?

    If you need any detail photos of CoB, let me know as I took pot loads when I was building my 7 mm Gladiator Duchess.

    Not sure Peter. Some sort of bracket. Haven’t got that far yet

    i also have a bunch of photos of 46235 taken earlier this year. My Finney7 build is stalled at the moment but has been a great experience.

    Looking good, Paul
