This version of the kit features round rear cab windows and standard depth bufferbeams.

The B4 was built by Avonside of Bristol from 1915 until 1934 when the company closed. Earlier versions had a rounded tank and later ones gained the more angular version. It was Avonside’s standard six wheeled industrial design and was used in ports, coal mines, ironstone quarries and more.

This kit was designed by Adam White to fit the Hornby Peckett B2 chassis and with a little modification can be altered to represent multiple members of the class.

The B4 is supplied in 3 main separate components to make sanding, paint preparation and detailing as easy as possible. This is because the 3D printing process, while being able to capture excellent detail, inevitably will have tiny layers on the surface which need to be sanded smooth wherever possible. We have found it easiest to paint all components separately and then glue together during final assembly.

Main Components:

Boiler and Saddle Tank, Cab, Running plate and bufferbeams

Separately fitted 3D printed accessories included:

Chimney, Dome/Safety Valve, Tank Filler Lid, Sandboxes, Buffers, Handbrake Column, Reverser, Firebox Backhead, Regulator

Separately fitted accessories included:

Handrail knobs x 9, .45mm Handrail Wire, Brass Smokebox Door Dart, Whitemetal Dummy Coupling Hooks x 2

We’ve tried to keep as many scale dimensions as possible, the main difference between this and the real thing is that the Peckett chassis has an offset wheelbase and slightly larger wheels than the Avonside, we have made the running board thicker for strength but kept the overall height of the loco the same. Hopefully these compromises are acceptable and the loco can become an asset to any industrial or heritage fleet!

Please note this kit will require a Hornby Peckett B2 chassis

3D Printing - please note that the raw 3D printed model will always have layers on the surface, there are some tips and tricks on smoothing them on the Railway Mania channel build videos. We do try very hard to get the highest print quality we can and check all models for defects before sale.
