NBR class L, LNER/BR Class C16 4mm scale loco kit. 
This photo is of No. 67489 and was built by Mr. Graham Dixon, one of our customers.  We are grateful to Graham for permission to use this photograph. ©G.M. Dixon 2014 all rights reserved.
This kit is now available, initially the kit will be in EM/P4 gauge but if enough interest is registered a OO version will follow.
The price for this kit is £104.95.  We can supply a modified Gibson wheel set giving the correct crankpin throw for an additioal £28.67, post free if ordered with the kit.  If you're modelling in the BR era then we have every smokebox number plate etched in 0.25mm nickel silver.  Each fret contains five numbers and costs £2.50 per fret.  Post free if ordered with the kit.  
Please state the era you're modelling and we will produce the rivet detail on the smokebox wrapper if necessary for you at no additional cost.  Some engines had smokeboxes replaced at Cowlairs works. Cowlairs practise was to use "snap head" rivets and this is quite a significant detail on the later engines.  The "as built" NBR engines had countersunk rivets and these smoke boxes were plain in appearance. 
When ordering it is most useful to us for the customer to include an email address and or a telephone number.  In the event of a query about your order this can save a lot of time.

For those of you who fit your locos with DCC chips you may find the next paragraph of interest. This item ws sent by a customer who has used one of our G5 Mk3 loco chassis under a Nu-Cast body.  The G5 has an 0-4-4 wheel arrangement and we feel that what works on a G5 would work equally well on any four coupled loco. 
Your (G5) chassis kit, works perfectly, superb slow running and a joy to build.  The body is Nu Cast with many mods.  Loco is DCC running on a TCS M1 decoder with a long delay " stay alive" system which overcomes any pickup problems from the 4 pickup wheels by storing and feeding back power. In fact the loco will run for  15 seconds with no power being fed in at all.  Also powers the flickering firebox.

This shot shows our fully compensated and load bearing chassis after being run on the test track.  The chassis features a waisted rear sectionto allow the radial truck to have 1.25mm movement eithr side if the chassis centreline.  the bogie is compensated and features prototypical double frames.  The compensation unit for the driving wheels features a custom 54:1, 2-stage reduction custom gearbox with the Mashima 1420D motor (not supplied) vertically mounted.  Provision is made to use Gibson plunger pickups so as not to detract from the prototypical brake gear and rigging.
