Here are files for a Sentinel Oil Fired Steam Engine. The files are full size so scale to suit your model. If scaled to 1/76 the model will fit directly onto the Hornby Sentinel 0-6-0 DH ready to run chassis.

These unusual looking steam engines were built in the mid 1950s and were used in steelworks. The basic chassis was adapted and used to develop a diesel version, the 0-6-0 DH.

Two cab types are drawn. Wire handrails will need to be added.

Enjoy
