A fantastic transformation, also a real treat to watch that 504 boiler power all of your Stuarts on steam! 

Thank you,  considering the state of it when i got it i thought i had bitten off more than i could chew...the picture you see on here is it after an all day soaking in white spirit just to remove the crud, The Stuart 504 is a fantastic boiler it kept those engines going much longer than in the video when i fitted a new bottle of gas on its next run, considering its piped up in 5/32 pipe on the outlet of the boiler to the engines it was amazing it was producing enough steam.... the working pressure was around 30 psi or 2 bar.... its a joy to watch and operate in the flesh turning individual engines on and off made me feel like a real boiler man ....Steve
