Corby Saddle tank

This was taken some twenty years ago at the KWVR's Oxenhope station. It shows a saddle tank engine bearing the name 'CORBY', doubtless after the steelworks where many such locomotives worked.

I have found reference to many different types of saddle tank but non with this particular pattern of shortened tank on an 0 6 0 wheel arrangement and with what I believe to be inside cylinders.

The Hunslet saddle tank which was the basis of the J96 austerities has a full length tank and outside cylinders

This drawing, by Roger West, shows a standard Hawthorn Leslie in its final guise as an oil-burner. It is from measured sketches of 14, which in the early months of 1971 was the Platelayers locomotive.

Any ideas anyone???
