Silver-soldered copper boiler, 100psi working pressure, feed by twin injectors, twin pop-type safety valves. Piston valve cylinders with Walschaert's gear, screw reverser in cab, twin mechanical lubricators.
A particularly well put together engine - lots of nice detail touches like the remote operated blowdown valve for the boiler and clock-type water gauge to show how full the tender is - it goes every bit as well as it looks. Steve and I had an afternoon down the club with it on Wednesday, we were both impressed - there's a clip here.
