A 3 inch scale Burrell 6nhp agricultural engine to the popular Plastow design. This one came in recently as part exchange against a Fowler road locomotive. Fairly basic standard of construction, however it runs in both directions.
The copper boiler was structurally sound on a twice working pressure hydraulic test, although with two leaky stays on the throatplate which will require repair before further use.
