Sorry i havent been on in a while. I have a wheeled frame at the moment, and have made other bits and pieces as time allows. Yes the loco will be based on the queen, but i will have a few more things on mine. I have a steam water pump and a air steam pump to put on. I am looking for a working steam turbo at the moment. Have sourced a 3 chime whistle which will be the ducks nuts i hope and have made a bell to suit. Have bought alot of other items such as safety valves, throttle valve with improved sealing seats, injectors, manifold valves, blow down valves etc. Have just tried to improve on what the Queen had. Just need the time and money to continue on. Will get there one day.
