Crazily it has been repaired before. The boiler intake fitting has been resoldered. Looks like the fitting was twisted and bent the boiler. It was repaired insitu with solder. The insulation has copped the brunt of the naked flame.
Not sure if i will push the boiler back into shape....possibly not.
Bit of a strip and bath in descaler.
Thinking i will descale most of the piping and do the steam,water taps and group head after. The piping is not as manky as the boiler
