One of the very few examples of slip eccentric valve gear to be used in full size - here for the inside cylinder - Webb's technically interesting if complex arrangement found little favour with his successor as CME, George Whale, all ten of the class being scrapped by 1907. Built in 1890, No.1311 "Celtic" was scrapped in 1906.
A well-built model, largely complete and having been fired in the past, although requiring paintwork to tender and parts of the locomotive.
It rolls freely and runs in somewhat desultory fashion in reverse, not in forward - the compounds are quirky things at the best of times, we suspect that some further attention to valves and their timing will be required.
The boiler has had a twice working pressure test with new certification issued, it held pressure well.
The chassis appears nicely made, with a good standard of machining.
