Hi all I'm sorry for the delay in thanking you for your help but had to take wife to Papworth for a mechanical heart valve. She wouldn't let me make it, can't understand it. However, thanks for your advice on fitting the boiler (brass angles) and have decided that there is suffient room to fit them under the foundation ring if I knotch the ashpan to suit.
