NBR Class "K", LNER/BR class D34 loco chassis designed to fit the PDK kits etched brass body. 
We intend to redesign this chassis in line with the revised chassis that will be supplied with our own D30 chassis. The proposed alterations will make what was a good chassis even better.  We would ask anyone who would like one of these chassis to please be patient.  We assure you it will be well worthwhile the wait.  The cost of the loco and tender chassis remains unchanged.
This chassis is available only in EM/P4.  If there's enough genuine interest from OO modellers then a OO version may follow.

 This is the first image of our fully compensated and load bearing NBR Class K, LNER/BR Class D34 loco chassis in EM/P4 scale.  The chassis has been designed to fit under the PDK body. The chassis was photographed sporting the Westinghouse brakes.  The later steam brake versions can be modelled too.  We have included extra etched parts and an additional brake cylinder to allow this.  (Please note that the Mashima motor is not supplied with the kit)  Wheels are by Alan Gibson.  The drivers are modified G4872S.  This allows the correct 10" throw to be used.  This photo was taken from about 30cm away from the subject and it's not obvious that the crankpin throw has been altered  The kit includes an NBR tender chassis compensated on all 6 wheels.  The price of this chassis kit is £55.00 including 2st class postage.

This chassis was built to show off the Westinghouse brake arrangement.  Extra parts are included to model the steam braked versions of the class that had the Westinghouse pump and brakes removed .

This ensures that the loco driving wheel cetreline remains remains parallel o the chassis centreline under all operating conditions. 
Chassis specification.
1.    This loco and tender chassis has been designed as a direct replacement for the chassis supplied with the PDK "Glen" loco kit.
2.    The chassis has been designed to be load bearing and compensated thus eliminating the smokebox heavy tendency on all 4-4-0 4mm scale model locomotives.
3.    Both loco and tender chassis are etched in 0.38mm nickel silver.
4.    Both chassis are "Fold up" construction eliminating the need for an expensive frame assembly jig.
5.    The bogie is compensated using the same method as the original with the external compensation beams bearing on the top of the turned brass bogie horn blocks.
6.    The mainframes have the prototypical inner frames at the front to clear the bogie profile.
7.    Original Westinghouse brake arrangerment comprising 8-hangers and shoes and 2-centrally placed operating cylinders.
8.    Revised brake gear for use after the Westinghouse pump was removed is supplied on a seperate etced fret.
9.    Custom 54:1, 2-stage reduction gearbox /compensation unit to optimise the drive and running qualities of the model.
