See [] (visited 7 November 2003) for details on this proposed TenWheeler compound by Richard Deeley.
In 1907, Sandham Symes drew up this four-cylinder compound that envisioned using 8" (203 mm) piston valves on all cylinders. According to the website's author "...a less-than-holy alliance between the Midland's general superintendent, Paget, and Deely's chief draughtsman, Anderson, resulted in the 4-6-0 being indefinitely postponed in favour of the unorthodox and unsuccessful locomotive known as the 'Paget Locomotive'."
The author adds that Deeley's resignation two years later probably stemmed from this choice. It's interesting to note that no other British Ten-wheeler was built as a compound, so speculation that this was a great loss to the Midland and the LSMR might be overdrawn.
