This pair of M7s use the Martin Finney kit for a basis on which to add all of the handmade Pull/Push fittings. For authenticity, these details entailed weeks of careful research, examination of photographs, draughting and fabrication before finally capturing the details of the prototype correctly. Turned brass replaces the kit's white metal chimney, dome and smokebox door. The models are 4mm scale to P4 standards. Painting and lining by Ian Rathbone.
