This is a set of parts to aid the construction of a 4-wheel Narrow Gauge coach body in 7mm scale (O-16.5 or 14mm)
 
This is a freelance model, designed in the bug box style. The set of cast resin parts (2 sides, 2 ends) allows rapid assembly of the coach body using just superglue or a general-purpose adhesive.  
 
This is a budget body only scratch aid pack, allowing the builder to construct or modify as they wish and fit a chassis of their choice according to gauge or design. A simple solution for O-16.5 would be to use a ready-to-run wagon chassis. The built example uses a Dapol 00 gauge wagon chassis.
 
Finished body size is aprox. 73mm x 41mm.
