Wagon constructors around the country followed RCH guidelines in manufacture but subtle differences in interpretation existed.  The model is founded on prototypes of the Gloucester Carriage and Wagon Works but, given the requirements of customers etc., and the need to accommodate liveries used on wagons generated by other manufacturers to the same design, some compromises have been made. The wagon is typical of those with internal dimensions in the range of 14'6" long, 7’ wide and 4’ deep.

Originally the stock may well have been produced with brakes on one side only.  The model represents stock either built with, or re-fitted with, brake gear on both sides in compliance with 1911 regulations.  This ought to allow maximum flexibility for modellers.  

                

 

Modern production techniques have been exploited to produce a model much closer to scale width than many competitors’ products:

• Scale thickness planking.
• Closer to scale width over solebars        
• Individually applied brakegear

To overcome the weight loss incurred in producing a scale body the model features an alloy weight in the base to which standard Arnold couplers are attached.  Modellers wishing to overcome the intrusiveness of this type of coupling will find it a simple matter to remove and replace it with more discrete variations.

Production of the coupler in transparent plastic allows the passage of light from trackwork and scenery to camouflage its presence in long trains.  Photographs of the model in a static, studio environment highlight the bulk of the coupler but in use it is quite discrete.

The model includes many fragile parts and is not capable of withstanding rough handling.
