Hi, At the Midlands ME there was at the stand of the Steamboat association a "new" type of boiler on show. It is a yarrow with instead of the usual straight tubes a series of coils. Looks awfully complicated when you see it but in my, and the builders opinion very effective. Thanks to "Funnel", the builder and Alan I could put up some pictures of it on my pages under the heading "Boiler" I know you hear me coming but I would be very interested to hear some comments of those who actually saw the boiler at the Midlands ME or from those who take trouble to have a look at the pictures.
