Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Thanks fella's.
I did eventually get the broken sight glass out yesterday.
Back story - someone through a friend found out that I'm into steam engines and they asked me if I could fix their childhood steam engine 'toy' that hasn't been out of its box for 25 years!
This is 25 years of water in a boiler......what do you reckon the rust is from?
