A nicely made four cylinder LMS Pacific, 6201 "Princess Elizabeth". Built by an exerienced engineer thirty years ago, it was test steamed when built then kept for display since - it's in pretty much "ex works" condition throughout.

Gunmetal cylinders with slide valves - outside valves actuated by Walschaert's gear with rocker arms to inside, screw reverser in the cab.
The boiler has had a twice working pressure shell test, the engine has been run on air in the workshop.
